maxabs!

maxabs!(r, A)

Compute the maximum absolute values over the singleton dimensions of r, and write values to r.

Examples

julia> r = [0, 0, 0];
julia> A = [-3, 2, -5];
julia> maxabs!(r, A)
3-element Array{Int64,1}:
 3
 2
 5

This example calculates the maximum absolute values of the elements in array A and writes the results to array r. The resulting array r contains the maximum absolute values for each corresponding element in A.

julia> r = [0, 0, 0];
julia> A = [1, -2, 3];
julia> maxabs!(r, A)
3-element Array{Int64,1}:
 1
 2
 3

In this case, since all the elements in A are positive or zero, the resulting array r will be the same as A itself.

Common mistake example:

julia> r = [0, 0, 0];
julia> A = [1, -2, 3];
julia> maxabs!(r, A')
ERROR: DimensionMismatch("arrays could not be broadcast to a common size")

In this example, the dimensions of r and A' (transpose of A) do not match, resulting in a DimensionMismatch error. Make sure to provide compatible arrays to the maxabs! function to avoid such errors.
