INPUT() allowed types matrix

[DrD]

I would like to use ONLY input TYPE(0), Real, or TYPE(4), vector:
This INPUT() [allowed types matrix], for vector v, doesn't work:

Code:


  INPUT ({ {v, [0,4], {25,70,1}},              
                {w, [4], {25,70,2}} }, 
                "Vector Projection", 
                {"Vector_v ", "Vector_w "}, 
                {"Input Vector v = [x,y,z], or Angle θ", "Input Vector w = [x,y,z]"},           
                {v,w}, 
                {} );

It does accept the v = Real, TYPE(0), but does not accept the v = [x,y,z], TYPE(4), in the allowable types matrix. What to do?
