Trying to produce a meshgrid 3D plot using surf graphs, error using *
显示 更早的评论
I am trying to make a surf graph for the equation:
Z=[ x(1-y)] / [(1+x)(x+y) ]
Here is what I have so far:
x = 0:1:100;
y = 0:10:1000;
[X,Y]=meshgrid(x,y);
Z=(x-x*y)/(x+x^2+y+x*y)
surf(X,Y,Z')
The error code is:
Incorrect dimensions for matrix multiplication. Check that the
number of columns in the first matrix matches the number of rows in
the second matrix. To perform elementwise multiplication, use '.*'.
Can someone please help me with this? I believe I am using multiplication correctly but I could very likely be wrong.

Read about element by element operations.
x = 0:1:100;
y = 0:10:1000;
[X,Y]=meshgrid(x,y);
Z=(X-X.*Y)./(X+X.^2+Y+X.*Y) ;
surf(X,Y,Z)
