isMonotonicDecreasing

isMonotonicDecreasing(X)

X is a scalar/vector.

Check whether the elements in X are monotonically decreasing.

a = [10,8,6,4,2]
isMonotonicDecreasing(a);
// output: true

a = [10,8,6,7,2]
isMonotonicDecreasing(a);
// output: false

a = [10,8,6,6,4,2]
isMonotonicDecreasing(a);
// output: true

a = [10,8,6,NULL,4,2]
isMonotonicDecreasing(a);
// output: false

a = [10,8,6,4,2,NULL]
isMonotonicDecreasing(a);
// output: true
