can anybody convert MATLAB code to c code ? please help

close all;
clear all;
clc;

n=4;
w=3;
h=3;

x=linspace(0,w,n);
y=linspace(0,h,n);

T=zeros(n);

T(1,1:n)=100; 
T(n,1:n)=20;
T(1:n,1)=30;
T(1:n,n)=40;

tol=1e-6;
error=1;
k=0

while error >tol
    k=k+1
    Told=T
        for i = 2:n-1;
            for j = 2:n-1;
                T(i,j) = .25 * (T(i,j-1) + T(i-1,j) + T(i+1,j) + T(i,j+1));
            end
        end
        error = max(max(abs(Told-T)));
end

subplot(3,1,1),contour(x,y,T),colormap
title('Temprature(Steady State)'),xlabel('x'),ylabel('y'),colorbar
subplot(3,1,2),pcolor(x,y,T),shading interp,
title('Temprature(Steady State)'),xlabel('x'),ylabel('y'),colorbar
subplot(3,1,3)
surf(T')
    xlabel('x')
    ylabel('y')
    zlabel('z')
    colorbar

The plotting part of that code has no C or C++ equivalent. Graphics is not part of the C or C++ programming language themselves.

The rest is straight forward. x is [0 1 2 3] . y is the same.

Then what i need to do ?

[Walter Roberson]

If you need the graphics, then you are going to have to locate a graphics package that you can call from your C code, and write the program in terms of using that. For example you might use gnuplot() http://www.gnuplot.info/

okay thank u so much
