A = [5 7 0; 0 2 9; 5 0 0]Every array in MATLAB has trailing dimensions of size 1. For multidimensional arrays, this means that a 3-by-4 matrix is the same as a matrix of size 3-by-4-by-1-by-1-by-1. Examples of multidimensional arrays with compatible sizes are: One input is a matrix, and the other is a 3-D array with the same number of rows and columns. B = reshape (A, 3, 2); % Reshape A into a 3x2 matrix. 2. Transposing a Matrix: You can change the dimensions of a matrix by transposing it. This swaps the rows and columns. Use the ' operator for matrix transpose:In Matlab, I need to multiply element wise two matrices of M x N and M x kN dimensions. In other words they are of the same height, but the second matrix is k times wider, so each element in matrix A must be multiplied by k elements of the row in matrix B.1 There are two things you need to keep in mind: MATLAB operates always along the first non-singleton dimension In a matrix, the first dimension is along rows and the second is along columns Within this principles falls array indexing. Another example, if you have a vector (abusing notation):S = std (A) returns the standard deviation of the elements of A along the first array dimension whose size is greater than 1. By default, the standard deviation is normalized by N-1, where N is the number of observations. If A is a vector of observations, then S is a scalar. If A is a matrix whose columns are random variables and whose rows are ...Divide Scalar by Array. Create an array and divide it into a scalar.
