wconv Performs 1D or 2D convolution. y = wconv (type, x, f) y = wconv (type, x, f, shape) type: convolution type. * 1 or "1" for 1D convolution. * 2 or "2" for 2D convolution. x: Signal vector or matrix. f: FIR filter coefficients. shape: * "full", computes the full one/two-dimensional convolution. It is the default value. * "same", computes the central part of the convolution of the same size as x. * "valid", computes the convolution parts without the zero-padding of x. It performs 1D or 2D convolution between the signal x and the filter coefficients f. Sonu Sharma, RGIT Mumbai (fellow at FOSSEE, IIT Bombay)
