to creat 'gabor' matrix

I am trying to create gabor matrix from your code but there is an error 'Undefined function or method 'gabor' for input arguments of type 'double'. How to solve it? code is as follows

close all;
clear all;
clc;

G = cell(5,8);
for s = 1:5
    for j =1:8
        G{s,j}=zeros(32,32)
    end
end
for s = 1:5
    for j = 1:8
        G{s,j} = gabor([32 32],(s-1),j-1,pi,sqrt(2),pi);
    end
end
for s = 1:5
    for j = 1:8        
        subplot(5,8,(s-1)*8+j);        
        imshow(real(G{s,j}),[]);
    end
end
for s = 1:5
    for j = 1:8        
        G{s,j}=fft2(G{s,j});
    end
end
save gabor G

Please format you code as explained in the "markup help" link on this page.

gabor() is not provided with any MATLAB toolkit.

There are some MATLAB File Exchange contributions that provide gabor routines.
