MATLAB: Linear interpolation in 3D space

3dinterpolation

by given 2 points in space: (x1,y1,z1), (x2,y2,z2) how can I make linear line between them and get bigger vector with x,y,z position i.e vector in size 3×100 – 3 to indicates x,y,z and 100 for the number of points (100 is just for example, it can be changed.

Easy, peasy. Pick two points (of my arbitrary choosing.)
P1 = [1 2 3];
P2 = [7 5 -2];
n = 100;
t = linspace(0,1,n)';
P = (1-t)*P1 + t*P2;
