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 […]

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.

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 […]
