3 D plot with three input and one output

I have input data in the form of matrix column. Coulmn 1 represent x1, column2 represent x2, Coulmn 3 represent x3. My output is the 4th column of the matrix as K.

I want to plot x1,x2,x3 on x,y,z axis and then want output K represent on the 3D graph

x1 x2 x3 K

Matrix= [ 9 3 4 324880.4

7 4 4 278983.1

5 5 3 256614.1

5 6 2 245502.9

4 7 1 240079.1

4 8 4 239987.4 ]

Pls provide the code to plot 3D graph for the above data

I assume x1,x2,x3 represent a line in 3d? How do you want to show K - as changes in the line colour?

Matrix= [   9  3  4  324880.4
    7  4  4  278983.1
    5  5  3  256614.1
    5  6  2  245502.9
    4  7  1  240079.1
    4  8  4  239987.4 ] ;

x = Matrix(:,1) ;
y = Matrix(:,2) ;
z = Matrix(:,3) ;
c = Matrix(:,4) ;
scatter3(x,y,z,1000,c,'.');
