immesh

Visualize 2D matrix using mesh plot, useful for frequency response visualization.

Syntax

immesh(imin,n);

Parameters

imin :

Input Matrix

n :

Number of points to plot

Description

This function used to visualize the 2-D matrix as 3D mesh plot with the values as the z-axes value. It is useful to visuallize the filter in frequency domain, and also the frequency response of the images.

Examples

f = fspecial('gaussian');
F = fftshift(fft2pad(f,256,256));
immesh(abs(F),100);
