MATLAB Programming

3 Basic Program Components
Function Output Separator
Spaces are allowed when specifying a list of values to be returned by a
function. You can use spaces to separate return values in both function
declarations and function calls:
function [data text] = xlsread(file, sheet, range, mode)
Slash and Backslash — / \
The slash (/) and backslash (\) characters separate the elements of a path or
directory string. On Windows-based systems, both slash and backslash have
the same effect. On UNIX-based systems, you must use slash only.
On a Windows system, you can use either backslash or slash:
dir([matlabroot '\toolbox\matlab\elmat\shiftdim.m'])
dir([matlabroot '/toolbox/matlab/elmat/shiftdim.m'])
On a UNIX system, use only the forward slash:
dir([matlabroot '/toolbox/matlab/elmat/shiftdim.m'])
Square Brackets — [ ]
Square brackets are used in array construction and concatenation, and also in
declaring and capturing values returned by a function.
Array Constructor
To construct a matrix or array, enclose all elements of the array in square
brackets:
A = [5.7, 9.8, 7.3; 9.2, 4.5, 6.4]
Concatenation
To combine two or more arrays into a new array through concatenation,
enclose all array elements in square brackets:
A = [B, eye(6), diag([0:2:10])]
