I found |plot::matrixplot| on mupad but it has two problems : * first it's on mupad but i want something that do the same on script environment * second it draw only these types of data : f(x,y)=z I want to draw a surface on matlab with numerical datas like : f(1,3,5) = 12 f(2,4,6)= 3 f(3,8,12)= 2 f(2,13,22)= 1 There's no function for f and all datas are number This is a sample of what i want but this one is for f(x,y)= z and my purpose is f(x,y,z)= w >

I found plot::matrixplot on mupad but it has two problems :

I want to draw a surface on matlab with numerical datas like :

 f(1,3,5) = 12 
 f(2,4,6)= 3
 f(3,8,12)= 2
 f(2,13,22)= 1

There's no function for f and all datas are number

This is a sample of what i want but this one is for f(x,y)= z and my purpose is f(x,y,z)= w
