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, :). DMObj: DataMatrix object, such as created by DataMatrix (object constructor).: Index1: A row or range of rows in DMObj specified by a positive integer or a range using the format x:y, where x is the first row and y is the last row.

Use numel to write data-type independent MATLAB code for array handling. MATLAB - 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. Using numel in your MATLAB ® code returns the same result for built-in types and fi objects. For example, on the first iteration, index = valArray(:,1). n numel(A) returns the number of elements, n, in fi array A. 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. 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.
