Vd = 0:0.1:0.7
P = ((0.6*Vd)-((Vd*1.5*10^-12)*(exp(38.64*Vd)-1)))
plot(Vd,P)
when i run this code itgives me error : Inner Matrix Dimension Must Agree ?
What changes should i do to get my code correct ?

There is no reason to use cell arrays for this code, and it actually causes the problem that you are experiencing. A very good data concept is to use the simplest array possible, unless a more complicated array is the only choice. In this case a simple numeric array holds all of that data quite nicely, so there is no need to use a cell array.
M = [0.0274 0.0268 0.0275;... 0.0130 0.0128 0.0124;... 0.0111 0.0108 0.0113;... 0.0110 0.0107 0.0107;... 0.0109 0.0107 0.0107;... 0.0109 0.0107 0.0107;... 0.0109 0.0107 0.0107;... 0.0109 0.0107 0.0107]plot(M,'-*')legend({'first','second','third'})creates this:
Summary: do not make data more complicate than it needs to be, it only makes the code more complicated!
PS: here is an easy way to convert that cell array into a simple numeric matrix:
M = vertcat(matrix{:});You need to use element-wise operator
y=(1./x) %^ put a dot here
