There exists a technique how to speed up matrix multiplication if it is done with explicit loops, here is an example in C#. It has a good idea how (potentially large) matrix can be split into smaller matrices. To contain these smaller matrices in MATLAB you can use cell matrix.

23 Feb 2011 “Element-wise” matrix vector multiplication in matlab · Multiply each matrix in a list of matrices against corresponding vector in list of vectors. 31 Jul 2004 A Matlab function mxmuleps has been programmed to reveal Matlab's roundoff threshold for matrix multiplication. This is smaller than eps, the MATLAB performs those loops for you, so you can write "x times A times x transpose" rather than writing matrix-vector multiplication functions. The main data Matrix Operations - MATLAB & Simulink, Answer to 110. Array multiplication works if the two operands point are vectors.

Learn more about binary multiplication, boolean multiply, boolean power Multiplication of pure imaginary numbers by non-finite numbers might not match MATLAB. The code generator does not specialize multiplication by pure imaginary numbers—it does not eliminate calculations with the zero real part. For example, (Inf + 1i)*1i = (Inf*0 – 1*1) + (Inf*1 + 1*0)i = NaN + Infi.

Also beware that a matrix is considered empty by MATLAB if any dimension of it is 0, so the matrices of size 5 x 0 or 0 x 17 or 0 x 0 would all be considered empty. MATLAB ® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices.

2019-10-22 · Figure 5: Addition of matrices in MATLAB MATRIX MULTIPLICATION: In order to multiply two matrices the number of columns of first matrix must be equal to the number of rows of second i.e. if the order of first matrix is (m X n), the order of second must be (n X r). The order of the new matrix will become (m X r)
