Question

0 个投票

First of all,greetings from Greece. i have real trouble with getting the i-v curve from a solar sell. I've written the function,and it seems right(when i run it,it returns a Ia value). Then i go to the matlab command window and i write: Va=0:0.01:2; plot(va,solar(va,suns,tac)) and what a see on the plot is a straight line and not a curve. PLEASE HELP
