We provide easy to use MATLAB code ( for calculating the Confined Gaussian Window (CGW) and Approximate Confined Gaussian Window (ACGW) which posses an optimal RMS time-bandwidth product. A single command w = replacewinbyCG(w); replaces a suboptimal window w from existing code by the Confined Gaussian window. The new window conserves the RMS temporal width and the square norm w'*w of the initial window.
