This code crashes my MATLAB and I don't know y figure(2); x = linspace(0,2); y = linspace(5,7); [X,Y]=meshgrid(x,y); Z = sin(X*Y).*Y + Y*exp(-cos(X*Y^2)).*X; mesh(X,Y,Z); xlabel('x'); ylabel('y'); zlabel('z'); grid on; title('Question 4 plot');

Hi, My MATLAB crashes when I try to execute this code,
MATLAB (R2015b) has stopped working
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
[close program]
I am not sure where I went wrong.
Original Question was
Use the meshgrid() and mesh() functions to plot the function z = sin(xy)+y exp(− cos(x^2*y)) over x ∈ [0, 2], y ∈ [5, 7]. Note you should turn the grid on, label the axes, and give the plot a title.
clear;
figure(2);
x = linspace(0,2);
y = linspace(5,7);
[X,Y]=meshgrid(x,y);
Z = sin(X*Y).*Y + Y*exp(-cos(X*Y^2)).*X;
mesh(X,Y,Z);
xlabel('x');
ylabel('y');
zlabel('z');
grid on;
title('Question 4 plot');

I know this doesn’t help, but with this assignment:
Z = sin(X.*Y).*Y + Y.*exp(-cos(X.*Y.^2)).*X;
your code ran for me without error.
------------------------------------------------------------------------------------------------
The first thing I would do is to put some fprintf statements in at various places, for example after the meshgrid call:
fprintf(1, '\n\tCall to ‘meshgrid’ successful\n')
and other places as appropriate. That can help if you don’t know where the crash is occurring. Then use the debugger functions to see what the problem is.
