Undefined function or method 'ge' for input arguments of type 'struct'.

This is my code,

 clear all; close all; clc;
 A = load('180-1-10001.mat')
 M = 10001;
 t = 0.2;      
 for i = 1:M,
        for j = 1:M,
            if A(i,j)>=t,
               A(i,j)=A(i,j)*1;
            elseif A(i,j)<=-t,
                A(i,j)=A(i,j)*-1
            elseif A(i,j)<=abs(t),
                A(i,j)=A(i,j)*0;
            end
        end
 end

Everytime I run it, I get the error message - "Undefined function or method 'ge' for input arguments of type 'struct'.".

I am not using any functions and dont have any variables/function with the name 'ge'. The .mat file that I am loading and the file I am working on are in the same directory. Please help.

Thanks, Rohan

When you use

A = load('something.mat')

then the result is a structure with one field for each variable that was stored in the .mat file. You can use fieldnames(A) to see what the names of the variables were.
