Check if all elements of cell array are equal to a certain value?

WebThe relational operators perform element-wise comparisons between two arrays. The arrays must have compatible sizes to facilitate the operation. Arrays with compatible sizes are implicitly expanded to be the same size during execution of the calculation. In the simplest cases, the two operands are arrays of the same size, or one is a scalar. WebSyntax B = flip (A) B = flip (A,dim) Description example B = flip (A) returns array B the same size as A , but with the order of the elements reversed. The dimension that is reordered in B depends on the shape of A: If A is vector, then flip (A) reverses the order of the elements along the length of the vector.

WebMATLAB ® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left to right. For example, consider a 3-by-3 matrix. You can reference the A (2,2) element with A (5), and the A (2,3) element with A (8).
