Error using plot Vectors must be the same length.

Hi everyone,

How can I change the size of Cfit in line 140 of the attached to double(30 x 8), in the attached code. When I run the code, I get error message:

Error using plot
Vectors must be the same length.

Error in fitting (line 145)
plot(tv,Cfit)

Hello @Dursman Before Plot please ensure that both Cfit and tv dimension should be same.

You have used the nesting of functions, within the code please check the following lines

tv=linspace(0,max(ExpTime),length(ExpTime));
Cfit=kinetics(theta,tv);

I think you can change the length of tv by considering more/or less data in

ExpTime=[600
    1200
...
....

Carefully look at the expressions, match the dimension then only go for the plot. Linspace documentation

Do the work, if you still unable to find it let me know.

Thanks a lot, KALYAN ACHARJYA. I am actually trying to reproduce the attached m-file by Igor Moura.

The dimensions of tv are 1*30 and Cfit are 1*8..how you can plot them? You cannot...to plot the dimensions of the inputs should be same.

I want Cfit to be 1*30 as well, I don't know how to do it.
