'Execution of script contour as a function is not supported'

trying to plot a compressor map with contours, when trying to run my code the error 'Execution of script contour as a function is not supported' shows up.

what does this mean?

my code fo the contour plot is

x = mdot(1,:,1);
y = PR(1,:,1);
[X,Y] = meshgrid(x,y);
Z = e(1,:,1);
contour(X,Y,X)

mdot, PR and e are all 1,5,5 doubles

the error also occurs when trying to run any of the contour examples from matlab.

You must have a contour.m in the path that is shadowing the built-in function contour(). run

which -all contour

please elaborate

[Walter Roberson]

At the MATLAB command line enter the command

which -all contour

The first one you see is likely one created by yourself, and you will have to rename or delete that file.

My guess is that that code you have shown us, you put into a file that you named contour.m but calling it contour.m interfers with being able to call Mathwork's contour function.

[Fangjun Jiang]

Run the above command in MATLAB Command Window. It will show you multiple files. You need to rename your own contour.m to something else to avoid the name conflict.

ah i see now, thank you both
