Function forEach #
Iterate over all elements of a matrix/array, and executes the given callback function.
The callback is invoked with three arguments: the current value, the current index, and the matrix operated upon. Note that because the matrix/array might be multidimensional, the “index” argument is always an array of numbers giving the index in each dimension. This is true even for vectors: the “index” argument is an array of length 1, rather than simply a number.
