what is the solution of this error?

Answer 1

[Star Strider]

This assignment:

t(1,:) = 20;

creates a (1x1) value for ‘t’, so in this assignment:

t(j+1) = 60*t(j,2)-59*t(j,1)+300;

‘t(j,2)’ does not exist.

One possible solution is to preallocate ‘t’ as:

t = zeros(100,2);
t(1,:) = 20;

before the loop.
