For a more general case (i.e. is a number in a given set), you have a few options. You could use the any function on the result of ... Operands, specified as symbolic equations, inequalities, expressions, or arrays. Inputs A and B must either be the same size or have sizes that are compatible (for example, A is an M-by-N matrix and B is a scalar or 1-by-N row vector). For more information, see Compatible Array Sizes for Basic Operations.MATLAB supports the multiple branching if statements which use the structure if – elseif – elseif- …. – else . The following example illustrates this. However we should point out that the word ifelse must be typed as a single word ( C++ supports a separated spelling as “else if “ because the use of curly brackets clarifies the block ...TF = ismatrix (A) TF = logical 0. Now determine whether the array elements of A are a matrix. Check whether the second page of the 3-D array is a matrix. The syntax A (:,:,2) uses a colon in the first and second dimensions to access all rows and all columns. TF = ismatrix (A (:,:,2)) TF = logical 1. Description. k = find (X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same orientation as X.

In this example, you can use the find function to locate all of the elements in A less than 9. I = find (A < 9) I = 8×1 3 6 7 11 14 16 17 22.Equality of Two Vectors. Create two vectors containing both real and imaginary numbers, then compare the vectors for equality. A = [1+i 3 2 4+i]; B = [1 3+i 2 4+i]; A == B. ans = 1x4 logical array 0 0 1 1. The eq function tests both real and imaginary parts for equality, and returns logical 1 ( true) only where both parts are equal.Matlab and Octave Programming for STEM Applications (Smith) 6: Conditionals Part 1 6.3: if, else, elseif Expand/collapse global location 6.3: if, else, elseif Page ID Carey Smith Oxnard CollegeDescription. TF = contains (str,pat) returns 1 ( true) if str contains the specified pattern, and returns 0 ( false) otherwise. If pat is an array containing multiple patterns, then contains returns 1 if it finds any element of pat in str. If str is a string array or cell array, then TF is a logical array that is the same size as str. MATLAB creates a cell array that contains all the values passed in for that argument. Functions can include only one repeating input arguments block. If the function includes both repeating and name-value arguments, declare name-value arguments in their own, separate arguments block after the repeating arguments block. ...An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. The elseif and else blocks are optional. The statements execute only if previous expressions in the if...end block are false. An if block can include multiple elseif blocks.Logical (Boolean) Operations True or false conditions MATLAB ® represents Boolean data using the logical data type.
