Maximum of a matrix along dimension X=1,2Īssigning a vector to a matrix column sliceīoundary handling, clipping (coordinate transforms) For example, let’s make a diagonal matrix from a given vector. Minimum of a matrix along dimension X=1,2 To make a diagonal matrix or to get the diagonal entries of a matrix, you can use the diag () function in MATLAB. Matrices passed by reference for efficiency More efficient is to create the resulting matrix using zeros(x), then use slice accessors to fill in the different parts. Quasar notes: please avoid because this programming approach is not very efficient. Missing values (IEEE-754 floating point status flags) ‘end’ variable, like in A(end,end) is currently not supported.Īll functions work transparently on the GPU (in MATLAB you need to use special datatypes ‘GPUsingle’, ‘GPUdouble’, …) Matrices are passed by reference rather than by value.
