Error is an easy I think? "Matrix is singular to functioning precision" and also my z(matrix) is complete of NaN with the critical collumn being complete of "-Inf".

I am unsure exactly how to correct this as I have actually introduced the formula for z mathematically exactly with appropriate parenthesis.

Code is together follows:

clf;

clear all;

xrange = -10:1:10;

yrange = -10:1:10;

xmat = repmat(xrange, length(yrange), 1);

ymat = repmat(yrange', 1, length(xrange));

z = (sin(sqrt(xmat.^2+ymat.^2)))/(0.1+sqrt(xmat.^2+ymat.^2));

mesh(xmat, ymat, z);

ANY help APPRECIATED many thanks :)

Your problematic heat looks like it's utilizing matrix division, however I'm guessing girlfriend want facet division. In other words, shot this:

z = (sin(sqrt(xmat.^2+ymat.^2)))./(0.1+sqrt(xmat.^2+ymat.^2));

FYI, i think her line would certainly be throwing a warning (yellow text) no an error (red text).

Omg i noticed the for the multiplication component but no for the division. That must solve it say thanks to you greatly. Likewise for explaining the error vs warning. Brand-new matlab user :)
