The function requires two inputs for the endpoints of the output vector, and it also accepts a third, optional input to specify the...Create two tables and divide the second table into the first. The row names (if present in both) and variable names must be the same, but do not need to be in the same orders. Rows and variables of the output are in the same orders as the first input. Since multiplying the input transform by the transfer function gives the output transform , we see that embodies the transfer characteristics of the filter--hence the name.. It remains to define ``z transform'', and to prove that the z transform of the impulse response always gives the transfer function, which we will do by proving the convolution theorem for z transforms.Each value of this matrix is equal to a formula as such: B (i,1) = log ( (S (:,:,1)/S0)/b) Where S (x,y,z) is a 115x94x64 matrix, S0 is a 115x94 matrix, and b is a constant value.
