I have created a model using pdetool command and kept the model under a function with name 'heat.m' as follows:

function A = heat (B,~)
Model = createpde('thermal','transient');
............
C = B/3.2;
E = C/5.;
..........
end

Calling the above function within a for loop in separate script file. The for loop are as follows:

t1=0:0.1:1;
for j=1:length(t1)
D(j) =.....;
A = heat (D(j));
end

I am not getting any results. I understand that I am doing wrong while calling input variable B. At each iteation, the variable B will be replaced by D(j). How can I replace the input variable correctly?

"I am not getting any results."

Please explain exactly what you expect, and what you observe (and how you are checking it).

"I understand that I am doing wrong while calling input variable B."

Why do you understand that? The most obvious bug I can see is the lack indexing into the output array, which means that your code will overwrite all A data except for the data from the last iteration.
