# Coloring a line based on height, gradient, or some other value in MATLAB8

MATLAB Answers is a great resource for getting help from the MATLAB community. There was a recent question that inspired this video. I took the question to mean, how can I change the color of a… 続きを読む >>

# Finding infrequent errors in MATLAB with DBSTOP if error

Some errors happen in MATLAB infrequently. If you don’t know the conditions when they occur, setting a breakpoint might not work. Using DBSTOP if error will have MATLAB stop on a line in the… 続きを読む >>

# Simple example of storing data as a matrix or structure

When we design a program, the way we store our data will have an effect on how our code looks as we manipulate that data later. In this video we had the choice to store the coordinates of a robot… 続きを読む >>

# Vectorizing code in MATLAB

When you vectorize code, you avoid looping through an array and instead do operations on the matrix level. This avoids for loops in MATLAB. The reason for vectorizing are often stylistic…. 続きを読む >>

# Interuptable callbacks and BusyAction in MATLAB5

If you push a button in a MATLAB UI and this starts a long calculation, what do you want to have happen if the user pushes the button a second time? Interuptable property and BusyAction property of… 続きを読む >>

# Using synthetic data to test algorithms in MATLAB2

This week we are making up some data and doing a couple of visualizations. We then modify the data to do a reality check on a simple algorithm. This allows us to gain confidence in our algorithm… 続きを読む >>

# Simplify, simplify, simplify1

I often say that one my greatest qualifications for troubleshooting MATLAB code is that I know I am not that clever, so I have to simplify things until I can understand them easily. It works really… 続きを読む >>

# Using Datetick with Plotyy in MATLAB6

Recently, I needed to plot two different sets of time series data on the same axes, but they were at different scales. In this simplified example, I show how you can change the x-labels to display… 続きを読む >>

# Exploring data through a series of vizualizations1

When we get unknown data, we do not always know where it will lead us. This video shows the series of visualizations that I went through to answer a question about my data. By showing the process,… 続きを読む >>

# Searching for permutations of a string in a list in MATLAB4

In this video a colleague was looking in a large list to see if each element was a permutation of any element of a shorter list. I name these lists Haystack and Needle so it is easy to remember… 続きを読む >>
