Personal Profile
I like to be outside. But if I'm inside, I like to be using MATLAB.
I'm an Application Support Engineer at MathWorks and civil/structural engineer by education.
Some Interests:
-Image Processing, specifically 3d images (CT, mri)
-All things graphics
-Optimization: both of code and objective functions
-Finite Element Analysis
The two things I want to improve on most are regular expressions and OOP.

Sean de Wolski submitted a Comment to Problem 796. Removing rows from a matrix is easy - but what about inserting rows?
Many of the test cases are wrong.
For example:
A = (1:2:10)';
IND = 1:5;
b = (2:2:10)';
y_correct = (1:10)';
y_correct should be [2:2:10,1:2:10]'
The zeros one has zeros that are the wrong size etc.
