ro=10;
ri=30;
t=0:0.1:1500;
ci=0.5
c_L=(ci*ri)/ro.*(1-exp(1).^((-ro.*t/.((ri-ro).*t+1500))));
plot(t,c_L)
MATLAB said it is [Error: File: test.m Line: 5 Column: 37
Invalid use of operator.]
I was trying to express equation
What can I do?

c_L=(ci*ri)/ro.*(1-exp(1).^((-ro.*t/.((ri-ro).*t+1500))));
should be
c_L=(ci*ri)/ro.*(1-exp(1).^((-ro.*t./((ri-ro).*t+1500))));
| You have /. instead of ./

In fact, MATLAB TRIED to tell you exactly where the problem lies.
c_L=(ci*ri)/ro.*(1-exp(1).^((-ro.*t/.((ri-ro).*t+1500))));

See that the red arrow points to the . in that line. It found something that made no sense. The error messages in MATLAB do try to be helpful where that is possible.
