Hey Girish,

In order to get weights of convolution function without using the for loop, you can use the "toeplitz" function to construct matrix where each column is a shifted version of the input signal. You can refer to the following documentation: https://www.mathworks.com/help/matlab/ref/toeplitz.html

You can use this function to construct arrays using which you can find the desired weights of convolution by performing matrix multiplication/ dot product.

You may take hints from the implementation of the "conv" function itself by referring to the "More About" section of the following documentation: https://www.mathworks.com/help/matlab/ref/conv.html#:~:text=length(u).-,More%20About,-collapse%20all

I hope this helps!
