Vectorization

One way to make your MATLAB programs run faster is to vectorize the algorithms you use in constructing the programs. Where other programming languages might use for loops or DO loops, MATLAB can use vector or matrix operations. A simple example involves creating a table of logarithms.

• x = .01;
  for k = 1:1001
     y(k) = log10(x);
     x = x + .01;
  end
  

A vectorized version of the same code is

• x = .01:.01:10;
  y = log10(x);
  

For more complicated code, vectorization options are not always so obvious.
