Convering 4 data vectors into 3d matrix

Question

编辑： Tala 2022-4-7

Hi, I have three vectors like this x=[1,2,3,1], y=[1,2,3,2] and z=[1,2,3,3] and a forth vector v=[10,15,20,25] which is dependant on x,y and z.

is there a way to make a 3D matrix representing the value of v in the space of x,y,z?

thanks!

You can use the fourth dimension as colormap. take a look at this. in your example you could use:

x=[1,2,3,1];
y=[1,2,3,2];
z=[1,2,3,3];
v=[10,15,20,25] ;
scatter3(x,y,z,40,v,'filled')    % draw the scatter plot
view(-31,14)

Thank you!

this helped to view the vector v in 3D plan. However my need is to represent the vector v in a 3*3 matrix form ?

I am bot sure if I understand the problem. You have x,y,z which are 1x4 and V which is 3x3. Your array dimensions should match before plotting
