In matlab you can type
>> help conv2
I am also trying to find it in C, but no success yet. I will try to make my own. It should be easy just some for loops and if conditions.

If your convolution kernel is [1 0 1] and you apply it to a 2-D matrix or an image, then it will interpolate the value for the middle pixel or point by average values of right and left pixels. It is a sliding window run from left to right on the image, shifting one pixel at a time and interpolating. This is done to find simple contrast edges in an image.
Hope this helps.
I was also hitting my head before I could understand it.

What are the structural differences between the C-terminus and N-terminus of a protein, and how do these differences impact the protein's function?
The C-terminus and N-terminus of a protein refer to the ends of the protein chain. The C-terminus has a carboxyl group, while the N-terminus has an amino group. These differences can affect the protein's folding, stability, and interactions with other molecules, which ultimately impact its function in the cell.
The primary function of NADH and FADH2 is?
The primary function of NADH and FADH2 is to transfer electrons in cellular respiration. These molecules are key players in the electron transport chain, where they donate electrons to help generate ATP, the cell's energy currency.
What is the difference between the N-terminus and C-terminus in a protein structure?
The N-terminus is the starting point of a protein chain, while the C-terminus is the end point. They are important for determining the overall structure and function of the protein.
How do you copy a function to another cell?
To copy a function to another cell, you can simply click on the cell containing the function, then use the keyboard shortcuts Ctrl+C to copy, and Ctrl+V to paste it into the desired cell. Alternatively, you can also click and drag the fill handle (a small square at the bottom right corner of the cell) to the cell where you want to copy the function.
What is the significance of the protein's N and C terminal regions in determining its structure and function?
The N and C terminal regions of a protein play a crucial role in determining its structure and function. These regions often contain important functional domains and binding sites that are essential for the protein's activity. Additionally, the N and C termini can influence the overall folding and stability of the protein. Therefore, understanding the significance of these terminal regions is key to understanding how a protein functions in the body.
C program for 2D convolution?
You can use ImageMagick library and use 'convolve' function.
Difference between linear and circular convolution?
circular convolution is used for periodic and finite signals while linear convolution is used for aperiodic and infinite signals. In linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular pattern ,depending upon the samples of the signal
Code for circular convolution matlab?
Please check the help files of the matlab circular convolution . Matlab already has a readymade function for it.
What is the difference between continuous and discrete convolution?
A convolution is a function defined on two functions f(.) and g(.). If the domains of these functions are continuous so that the convolution can be defined using an integral then the convolution is said to be continuous. If, on the other hand, the domaisn of the functions are discrete then the convolution would be defined as a sum and would be said to be discrete. For more information please see the wikipedia article about convolutions.
What is convolution in science?
Convolution in science is a mathematical operation that combines two functions to produce a third function representing how one function modifies the other. In image processing and signal processing, convolution is used to process and analyze data by applying a filter or kernel to an input signal. It is a fundamental concept that allows for extracting features or enhancing signals in various scientific fields.
Why is the need for circular convolution?
for finding convolution of periodic signals we use circular convolution
What is the function of the Pre Central gyrus?
The precentral gyrus is the posterior convolution of the frontal lobe. The function is to control voluntary muscle movements in the body.
What is convolution?
In mathematics and, in particular, functional analysis, convolution is a mathematical operator which takes two functions f and g and produces a third function that in a sense represents the amount of overlap between f and a reversed and translated version of g. A convolution is a kind of very general moving average, as one can see by taking one of the functions to be an indicator function of an interval. we mainly use impulse functions to convolute in dicreate cases
Can you perform a linear convolution from circular convolution?
yes we can perform linear convolution from circular convolution, but the thing is zero pading must be done upto N1+N2-1 inputs.
Diff between linear and circular convolution?
there is a big difference between circular and linear convolution , in linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular patteren ,depending upon the samples of the signal
State and prove convolution theorem for fourier transform?
Convolution TheoremsThe convolution theorem states that convolution in time domain corresponds to multiplication in frequency domain and vice versa:Proof of (a):Proof of (b):
Applications of Circular convolution?
for finding convolution of periodic signals we use circular convolution
