# A Case for Divergence between MATLAB and C14

Posted by Loren Shure,

There are some functions in MATLAB that we designed to be similar to their counterparts in other languages. There are also some functions that we deliberately designed differently. A case in point is the syntax and behavior for the switch... read more >>

# Fourier Transforms!

Posted by Loren Shure,

I wanted to point out to all of you interested in Fourier transforms that Steve is in the midst of posting a collection of wisdom on this topic. Discussions talk about nomenclature, discrete vs. continuous transforms, normalization, and more. You'd be well served... read more >>

# Carving a Dinosaur36

Today I’d like to introduce a guest blogger, Ben, who is consultant over in The MathWorks UK. Some of you may have come across his customer projects and demos on image processing. He’s going to talk about one of those demos here. ... read more >>

# How to Check for Existence of Solution to Matrix Equations6

Posted by Loren Shure,

There was a great question on the newsgroup this past week asking how to determine if a system of equations had a solution. The poster wasn't (at least yet) concerned with what the solution was. ... read more >>

Posted by Loren Shure,

There continue to be a flurry of queries suggesting that MATLAB has bugs when it comes to certain operations like addition with more than values. Sometimes what prompts this is a user noticing that he or she gets different answers when using... read more >>

# Unique Values Without Rearrangement4

Posted by Loren Shure,

In MATLAB, the simplest form of the function unique returns the unique values contained in a numeric vector, with the results sorted. This is often acceptable, but sometimes a user prefers the results in the order originally found in the data. ... read more >>

# Coordinating Zero Removals from Multiple Arrays13

Posted by Loren Shure,

I've fielded some questions recently about how to coordinate multiple arrays changing simultaneously. One example is removing elements for two arrays in the case where either array holds a zero for the location. This is a good opportunity to reiterate ... read more >>

# Empty Arrays with Flow of Control and Logical Operators17

Posted by Loren Shure,

After reading last week's post on calculating with empty arrays, one of my colleagues mentioned some other behaviors with empty arrays that have tripped him up in the past. Today I will discuss how empty arrays work in the contexts of flow... read more >>

# Calculus with Empty Arrays24

Posted by Loren Shure,

MATLAB has had empty arrays since before I started using the program. When I started, the only size empty array was 0x0. When version 5 was released, empty arrays came along for the N-dimensional ride and got more shapely. ... read more >>
