WebA matrix is a two-dimensional array often used for linear algebra. Array Creation To create an array with four elements in a single row, separate the elements with either a comma (,) or a space. a = [1 2 3 4] a = 1×4 1 2 3 4 This type of array is a row vector. To create a matrix that has multiple rows, separate the rows with semicolons. WebTo multiply matrices they need to be in a certain order. If you had matrix 1 with dimensions axb and matrix 2 with cxd then it depends on what order you multiply them. Kind of like subtraction where 2-3 = -1 but 3-2=1, it changes the answer. So if you did matrix 1 times matrix 2 then b must equal c in dimensions.
