Min / Max of a vector (finds the first appearance of the minimum/maximum)

[sim, index, value] = ld_vector_minmax(sim, events, in, findmax, vecsize)

Function is buggy somehow. Find maximum should work. Minimum perhaps not!

in *+(vecsize)

findmax greater than 0 means "find the maximum"

index * - the index starting at 1, where the max / min was found

value * - min/max value
