Show 1 more comment. 4. If there some good reason why you can't use the inbuilt, you can use a convolution instead. Cross-correlation is simply a convolution without the reversing, so to 'undo' the reversing of the correlation integral you can first apply an additional reverse to one of your signals (which will cancel out in the convolution). Expert Answer. Task 2 -Performing Convolution using MATLAB Exercise: MATLAB has a function called conv () which can perform convolution on two functions (see Table I for useful information and syntax for this function). For this task you will be required to find and graphically present the output from a system with the impulse response and.
