This message occurs when you use variables that are not defined. For example:
y=5*t
How Matlab will calculate 5*t if the variable t is not defined. the correct code is for example
t=10
y=5*t

If you had that line in a function, then the variable would be removed from the workspace as soon as that function returned.
Also, if you have a "clear" then you might be destroying the values. You should almost never have "clear all" in a program.
