Hi
I want to make the following code as a function. I want to call this code as function in another code to get the 'T' values.
[T_20]=xlsread('20.xlsx','sheet2','C2:C2243')
[alpha_20]=xlsread('20.xlsx','sheet2','F2:F12243')
for i=1:8
x(1)=0.1
x(2)=0.2
x(i+1)=x(i)+0.1
for j=2:2242
if x(i)>alpha_20(j)
X2_20(i)=alpha_20(j+1)
X1_20(i)=alpha_20(j)
Y2_20(i)=T_20(j+1)
Y1_20(i)=T_20(j)
end
end
T (i)=(((Y2_20(i)-Y1_20(i))/(X2_20(i)-X1_20(i)))*(x(i)-X1_20(i)))+Y1_20(i)
end
Thanks

See the documentation for Function Basics to get you started.
You already know you want it to return ‘T’, so you need to define what (if any) inputs you want for your function

Thanks. Its working. I did a mistake by calling the 'T' and 'D' separately in the main code.
I came up with one more doubt. I need to plot the graph between the 'T_a' (loaded from excel) and 'D'(calculated in the loop) for each file in a single figure. As we are not storing the data loaded from excel files, how to make the graph?
we must store the 'T_a' values to plot the graph (or) we have some other alternative approach?
Thanks

You can always return the ‘T_a’ values just by adding it to the returned values:
function [T,D,T_a] = ExcelRead(prefix)
and as before:
[T{k1},D{k1},T_a{k1}] = ExcelRead(prefix);
