Hello everyone,
Does anyone know why I just get NaN as a result?
D=giuliayearlyDELTA2.Height;
E=str2double(D);
NEW_4=E *0.35 *10;
Thank you!

There is one NaN value in ‘giuliayearlyDELTA2.Height’.
However, the str2double call is not necesary.
Just do:
D = giuliayearlyDELTA2.Height
NEW_4=D *0.35 *10;
.

D=giuliayearlyDELTA2.Height;
E=D;
NEW_4=E *0.35 *10;
D is not a string. You need not to ue str2double; already D is in double.

Ran in:
First, Height is already double, so
A = 2;
str2double(A)
ans = NaN
Secondly, first element of Height is NaN. Remove it prior to the analysis.
