Matlab is useful in image processing in order to convert the image into a matrix and make several operations on it.

i want to do validation to my image folder
Matlab has a built-in function called "demod" in the communications (signal processing) toolbox where you can specify 'fm' for frequency demodulation.
Please ask clearly what you want to do with the image and explain why a nested for-loop is necessary.
imhist(x); where 'x' is your data or image to find histogram.

Mat lab has got a predefined command for this purpose. The command is 'imread'. Syntax: A = IMREAD(FILENAME,FMT) It reads a grayscale or color image from the file specified by the string FILENAME. If the file is not in the current directory, or in a directory on the MATLAB path, specify the full pathname.
I also want to know ! please anyone give us some suggestions
Assuming that the receiver uses a high-side local oscillator and an IF of 455 KHz, the image frequency is 910 KHz above. When tuned to 1600 KHz, the image frequency would be 2,510 KHz.

Ans:The purpose of frange in DTFT.m is to set the range of frequency in order to observe spectra of the signal
