MATLAB Vectorization Demystified – Part 3: Preallocation

“MATLAB Vectorization Demystified”: In this series, I try to explain vectorization operation in MATLAB in details step-by-step through several examples. This is part 3 in which “preallocation” of variables/parameters are explained. Preallocation You probably have seen this MATLAB warning when coding for or while loops: This is the fact that for and while loops that […]

MATLAB Vectorization Demystified – Part 2: Matrices and Indexing

“MATLAB Vectorization Demystified”: In this series, I try to explain vectorization operation in MATLAB in details step-by-step through several examples. This is part 2 in which “Matrices and Indexing” are explained. Matrix definition Every variable in MATLAB is an array that can hold many numbers, characters, strings, date and times, and so on. Arrays in […]

MATLAB Vectorization Demystified – Part 1: Vectors and Indexing

“MATLAB Vectorization Demystified”: In this series, I try to explain vectorization operation in MATLAB in details step-by-step through several examples. This is part 1 in which “Vectors and Indexing” are explained. Vector Definition in MATLAB In MATLAB, a vector is a matrix with either one row or one column. sampleVector1 = 1 2 […]

Latex: Table content and border colors

Sometimes, it is required to have the content of a table in a different colour. If only specific elements of a table should be in different colour, \color{colour}{text} can be used easily. If we need to change the colour of the contents to a single colour different from the main colour of the document, we […]

Machine Learning with MATLAB

A bunch of machine learning techniques are implemented on real data in here. The approaches are used for clustering, classification, deep learning, and regression through examples.

Changing blank space before and after figure captions in IEEE format

The IEEE format creates generous (and more than enough) blank space before and after the figure captions, which cannot be seen in the IEEE published papers. When I had a look in to the IEEEtran.cls class, I found the settings similar to this: So, the above and below caption skips are set as it is […]

Resolving issue of tables in the IEEE Latex class

subfig package is a unique package in to create subplots with specialised caption and label. Using the package in the IEEE class, however, causes an issue in the tables captions. Per IEEE format, captions should be in small caps (except a, an, to, or, and, …). The table number should come before the text of […]

Turning off warning message issued by some built-in functions in MATLAB

Sometimes, MATLAB built-in functions throw warning messages in the Command Window. I am not talking about the sort of messages which can be easily handled by setting an option before calling the function. For instance, output messages during optimisation iteration can be conveniently controlled by the available options. However, there are other types of warning […]

Scatter and line plots with gradient colour on y-axis direction in MATLAB

Recently, I needed to plot a bunch of time series with gradient colour on the y-axis direction. I wanted the colour to change based on the value of y for each cluster of x. For instance, if you have 10000 days of hourly data, where you want to plot these days in a figure with […]

Using “minted” package in Latex to format programming codes on Windows machines

I was looking for a package to format programming code inside document for a specific programming language. There are two popular options, which are minted and listings. Between the two options, I found minted more flexible and easy to use, of course only when installed. It allows you to easily specify the programming language of […]
