Here is the matrix

isCategoricalPrd = [false, false, false, false, false];

I want to know the type of matrix members and how to make this matrix systematically like in neumerical matrices "zeros" or "ones" are used so that I can make them with any size.

false and true are datatype named logical

true(1,5)
false(1,5)
ones(1,5,'logical')
zeros(1,5,'logical')
logical(ones(1,5))
logical(zeros(1,5))

It does not return the interested matrix:

isCategoricalPrd = false(1,5)
isCategoricalPrd =
  1×5 logical array
   0   0   0   0   0

categorical(false(1,5), [false, true ] )
