Plotting a stream function in matlab
How does one do this?
I am trying to plot
PSI = Acos(6x)-Uy where A=1 and U=1 over an x range of -2000-200 and y from -2000-2000
My code is this and it is giving me an error.
x = -2000:1:2000;
y = -2000:1:2000;
si = zeros(x,y);
for x = -2000:1:2000
for y = -2000:1:2000
si(x,y) = cos(6*x)-y;
Thanks for any help

Something that looks like this

I never used Matlab, but from the error description
for x = 0:1:4000
for y = 0:1:4000
si(x,y) = cos(6*(x-2000))-(y-2000);
"Everyone knows the inch is better than the centimeter, because it is bigger."

In MATLAB arrays always have a lower bound of 1. Your for loops have to be adjusted. Also I think contour() is more suitable instead of plot(). Then you can specify the x- and y-axis units.
