Another important note to make is that is possible to take determinants of larger size square matrices (larger than ). However, this will not be necessary for most purposes except when we are dealing with diagonal and upper triangular matrices defined above. If we have an upper triangular and diagonal matrix of …

Two matrices A and B are the same if all their entries agree. (We can only compare matrices of the same size.) Matrices of the same size can be added. Suppose that A and B are matrices. Then . is a matrix with entries. for and . Matrix addition satisfies the following two properties: Matrices in MATLAB. To generate a vector in MATLAB, type, for ...

Students have been working with matrices since Grade 9 and have been performing various operations with number arrays. However, a review of the terminology involved with matrices would be beneficial for the students. A matrix is a rectangular array of numbers enclosed by parenthesis. Matrices are usually named using upper case letters.
