MATLAB: Extract a number from 1*1 cell

cell arrays

I have

tbl2 = 1*1 cell array 
{[1.29]}
Name      Size            Bytes  Class    Attributes
  tbl2      1x1               112  cell

How can one extract a double from this cell array?

value = tbl{1} % Extract 1.29 from the cell

I think you should really read the FAQ so you get a good intuitive feel for how to use cell arrays and when to use braces, brackets, and parentheses:

NewCellArray = vertcat( ExistingCellArray{:} );

First, t and current need to be of same size, both 1x10028 (or 10028x1) vectors. So, for example, use

t = linspace(1,10,10028);
plot(t, current);

Note, that in the above case, time is an evenly spaced vector, starting at t=1 and ending at t=10 .
