no way... use awgn function in matlab
You would have to write your own code for a modulation (Matlab has a convolution function not in the tools), otherwise you can use its built in function in the signal processing toolbox.
To implement the Runge-Kutta 4(5) method in MATLAB for solving differential equations efficiently, you can use the built-in function ode45. This function automatically selects between the fourth and fifth order Runge-Kutta methods based on the error estimates. Simply define your differential equation as a function and provide it to ode45 along with the initial conditions and the desired time span. MATLAB will then solve the differential equation using the Runge-Kutta 4(5) method and provide the solution efficiently.
You can compute sin(x) manually/numerically using Taylor's Series.
You can do this by selecting the sequence of images you want to animate and then using the Matlab's function called "im2frame". This will result in a video.
Some function are not using in c
To programmatically stop a MATLAB script execution using a single command, you can use the "return" command. This command will immediately exit the current function or script, effectively stopping its execution.
To calculate eigenvalues and eigenvectors in MATLAB using the 'eig' function, the syntax is as follows: eigenvectors, eigenvalues eig(matrix) This command will return the eigenvectors and eigenvalues of the input matrix in a specific order.
To calculate and sort eigenvalues efficiently using MATLAB, you can use the "eig" function to compute the eigenvalues of a matrix. Once you have the eigenvalues, you can use the "sort" function to arrange them in ascending or descending order. This allows you to quickly and accurately determine the eigenvalues of a matrix in MATLAB.
To calculate a double integral using the trapz function in MATLAB, you can first create a grid of points for the two variables you are integrating over. Then, evaluate the function you are integrating at these points to create a matrix of function values. Finally, use the trapz function twice - once along one dimension and then along the other dimension - to compute the double integral.
To convert Arabic numerals to Roman numerals using a GUI in MATLAB, you can create a simple application using the uicontrol functions. First, design the GUI with input fields for the Arabic numeral and buttons for conversion. In the callback function for the conversion button, implement the logic to convert the Arabic numeral to Roman numerals. You can use a series of conditional statements or a lookup table to perform the conversion and then display the result in a designated output field.
plot(abs(fft(vectorname)))the FFT function returns a complex vector thus when you plot it, you get a complex graph. If you plot the absolute value of the FFT array, you will get the magnitude of the FFT.
