i have used the ode23() function, to find a solution of some differential equations. As out put i gives me a cetor "t", and a matrix "x" with the solutions.
The problem is that i can't see the calculated values in the "x" matrice. in the works space window there is no problem, and for example the first column of the matrix looks something like this:
but if i type "x(:,1)" in the command window, this is my output:
why does it say 1.0e+18 ?
if i type "x(4,1)" i'll get this:
so clearly the numbers are there, but i can't see them or use them, because of the 1.0e+18
This gives me a problem when i want to use the solution to calculate something, and it also gives me a problem if i want to plot the solution. I just can't see anything but zero unless the numbers get large enough, which they does at the end of the timescale.
does anybody know, why this happens?
