Working with 8-Bit and 16-Bit Images

8-Bit and 16-Bit Indexed Images Double-precision (64-bit) floating-point numbers are the default MATLAB representation for numeric data. However, to reduce memory requirements for working with images, you can store images as 8-bit or 16-bit...

Stream Line Plots of Vector Data

Wind Mapping Data The MATLAB vector data set called wind represents air currents over North America. This example uses a combination of techniques: Stream lines to trace the wind velocity Slice planes to show...

Matlab Using FFT

This demonstration uses the FFT function to analyze the variations in sunspot activity over the last 300 years. Sunspot activity is cyclical, reaching a maximum about every 11 years. Let’s confirm that. Here is...

Adding Text Annotations to Graphs

What Are Text Annotations? Text annotations are boxes containing text strings that you compose. The box can have a border and a background, or be invisible. The text can be in any installed text...

Finding maximum and minimum values in arrays

Let’s write a function file range.m that calculates the difference between the maximum and minimum value in a vector. The file should return a reply. Open an edit window. Create a function file like...

bsxfun – Apply element-by-element binary operation to two arrays with singleton expansion enabled Syntax C = bsxfun(fun,A,B) Description C = bsxfun(fun,A,B) applies an element-by-element binary operation to arrays A and B, with singleton expansion...

arrayfun

arrayfun – Apply function to each element of array Syntax A = arrayfun(fun, S) A = arrayfun(fun, S, T, …) [A, B, …] = arrayfun(fun, S, …) [A, …] = arrayfun(fun, S, …, ‘param1’,...
