How to plot "f(x,y) = e^-(x^2+y^2)" function in matlab?

Undefined function or variable 'y'.

Error in Untitled (line 5)

y = exp(x.^2+y.^2);

my computer gives these errors and I do not know how to fix them.

Try "surf".

[Beyza Taka]

That hasn’t changed

Try this:

figure
fsurf(@(x,y)exp(-(x.^2+y.^2)), [-2 2  -2 2])

A blank page opening., not a graphic.

[Torsten]

Try again. I corrected a little typo.

[Star Strider]

I have no idea what the problem is.

I copied working code (that runs without error in R2020a) based on the posted ‘exp(x.^2+y.^2)’ expression:

figure
fsurf(@(x,y)exp(x.^2+y.^2), [-2 2  -2 2])

and produced the correct plot:

The function in the title:

figure
fsurf(@(x,y)exp(-(x.^2+y.^2)), [-2 2  -2 2])

produces:

again without error in R2020a.

Thank you very much.I guess I couldn't because my Matlab version was old.I tried it online in the 2020 version and the graphics came out.

My pleasure!

Can you also suggest for me what range would i change if i want to draw the function f(x,y)=(x^(2)+y^(2)) ℯ^(y^(2)-x^(2))

@Nguyet Nguyen You should have posted a link to your question. That way you avoid double effort.

The proof of the pudding is in the eating.
