The input valArray can be of any MATLAB data type, including a string, cell array, or struct.

The loop executes for a maximum of n times, where n is the number of columns of valArray, given by numel(valArray, 1, :). For example, on the first iteration, index = valArray(:,1). Increments index by the value step on each iteration, or decrements when step is negative.Ĭreates a column vector index from subsequent columns of array valArray on each iteration. Increments the index variable from initval to endval by 1, and repeats execution of program statements until index is greater than endval. Values has one of the following forms − Sr.No. Pre-allocation is addressed in the second half of the video. There are two types of loops: for statements loop a specific number of times, and keep. A for loop is used to construct a simple matrix with an underlying pattern. Each repetition of the process is called an 'iteration', and the results of. Repeating then means looping or cycling a process usually with the objective of approaching a desired goal or target. Program (1): To print number 2 four times.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. Loops can be nested, to preform iterated task within another iterated task. With loop control statements, you can repeatedly execute a block of code. The MATLAB iteration structure ( for-loop ) repeats a group of statements a fixed, predetermined number of times. MATLAB while loop executes statements repeatedly an indefinite number of times as long as expression(1) evaluates to true condition. Program (2): To print a table of any number, enter by user. for k=1:2Ĭreate a script file in MATLAB and type the following code – Program (1): To print number 5 two times.

MATLAB for loop first initialize the variable with the initial value then execute statements after that increment the variable value by 1 and do this again and again until the variable value reaches to the final value. General Form: for variable = initial value : final value MATLAB for loop executes statements a specific number of times. MATLAB loops are generally used for executing the block of statements repeatedly along with tracking of each iteration with an incrementing index variable.

That’s why MATLAB provides us, a repetitive structure called loop. In real life, many times we need to perform some task repeated over and over, until a specific goal is reached.

After reading this MATLAB Loop topic, you will understand loop types and you will know the for and while loops theory, and examples.
