# Basics: Finding a subset of a matrix13

Posted by Doug Hull,

Imagine you have a matrix, and you want to make a subset of that matrix that has only the rows that have a 2 in the first column. This is how you would do that. … read more >>

# Advanced: Loading, filtering and displaying geographic data with the Mapping Toolbox.

Posted by Doug Hull,

This short video uses the Mapping Toolbox to load in the state boundaries in a given area and display them on a special map axis. Random points are also generated and filtered based on their location. @media (min-width: 992px) { .containing-block { width: 100%; } } … read more >>

# Advanced: Making a sweeping slice through volume of data.7

Posted by Doug Hull,

A MATLAB user recently asked how we could make a visualization similar to this one. I was a little surprised that we were able to do the visualization, with interactivity in less that 15 lines of code. %% d = flow; d = shiftdim(d,2); x = 25; y = 26; z = 21.59561; v = 3.22068; h… read more >>

# Basics: Volume visualization: 9/9 Unifying example8
