MATLAB Programming 36 - for loop

The for Loop

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.

Syntax

The syntax of a for loop in MATLAB is:

for index = values
     <program statements>
             ...
end

values has one of the following forms:

initval:endval - increments the index variable from initval to endval by 1, and repeats execution of program statements until index is greater than endval.

initval:step:endval - increments index by the value step on each iteration, or decrements when step is negative.

valArray - creates a column vector index from subsequent columns of arrayvalArray on each iteration. For example, on the first iteration, index = valArray(:,1). The loop executes for a maximum of n times, where n is the number of columns of valArray, given by numel(valArray, 1, :). The input valArray can be of any MATLAB data type, including a string, cell array, or struct.
