function y = wconv (type, x, f, shape)
//Performs 1D or 2D convolution.
//Calling Sequence
//y = wconv (type, x, f)
// y = wconv (type, x, f, shape)
//Parameters
//type: convolution type.
//x: Signal vector or matrix.
//f: FIR filter coefficients.
//shape: Shape.
//Description
//This is an Octave function.
//It performs 1D or 2D convolution between the signal x and the filter coefficients f.
//Examples
//a = [1 2 3 4 5]
//b = [7 8 9 10]
//wconv(1,a,b)
//ans =
// 7 22 46 80 114 106 85 50
