Linspace using matrix input matlab

Question

My question seems wierd, because I know that we can\'t use a matrix as input in linspace(x1,x2,n) function. But my question is more something like : I have a ve

Answer 1

Maybe something using interp1, to interpolate something like:

[0    0    0    ... 0 ]
[A(1) A(2) A(3) ... A(N)]

with N rows .... For instance:

N = 5;
Amax = 15;
A = linspace(0, Amax, N);

x = [0 1];
y = zeros(2, N);
y(2, :) = A;

B = interp1(x, y, linspace(0, 1, N))

Which will give:

B =

     0         0         0         0         0
     0    0.9375    1.8750    2.8125    3.7500
     0    1.8750    3.7500    5.6250    7.5000
     0    2.8125    5.6250    8.4375   11.2500
     0    3.7500    7.5000   11.2500   15.0000

Not sure it will be any faster than a for loop or that even get the point here :)
