I love the MATLAB contest, one of the great things about working at The MathWorks is I get to ‘play test’ the contest before it goes live. One of the bad things about working at The… read more >>

Two minute video shows how to fit a surface to nonuniform data.
Real data is not always on a nice X,Y grid, but the MATLAB commands
SURF and MESH expect them to be. GRIDDATA and MESHGRID help to fix… read more >>

Two minute video shows how to validate GUI input. This makes sure that user input will not break your code. This example makes sure that the edit box value is not greater than twelve. This technique… read more >>

When I look at code written by new users, sometimes, I will see code like this:
