WebHence, if you are looking for a matrix X such that A ⋅ X = B, X is denoted as X = A ∖ B. X = B / A means you are dividing by the matrix A on the right and X = A ∖ B means you are dividing by the matrix A on the left. Also, just like division by zero is not possible in the context of real numbers, you cannot divide by certain matrices ...

WebThis is some of the confusion that has cropped up thanks to MATLAB's new automatic dimension broadcasting. First of all, note that the ./ operator is an element-wise operation. In versions of MATLAB prior to R2016b, use of this operator would require the two inputs to be exactly the same dimension. [1 2] ./ rand(4) Matrix dimensions must agree.
