%matrix a of indoor temp
%matrix b of outdoor temp
t=5
for i=1:8590
dt=(a(i+1)-a(i))/t
c=dt/b(i)-a(i)
plot(c)
not great at matlab
aim is to produce a graph of a constant that varies over time. although i dont know how to add the data file into the matrix?
once ive added the matrix, does this code run and will it produce a graph of c as an output
thanks for any help

"...although i dont know how to add the data file into the matrix?"
What "data file" ? You don't mention any files anywhere else in your question.
You probably don't need a loop, take a look at diff and element-wise division.

Assuming matrixes a and b are the same size.
dt=diff(a)/5;
c=dt./(b(1:end-1)-a(1:end-1));%diff(a) will be one less than matrix a and b
plot(c);
Yes, it plots c.

Please provide a copy or example of your data file. Do you not know how to load the data file into matlab?

You forgot to attach your data file. Please attach it. In the meantime, try importdata(), readtable(), dlmread(), csvread(), readmatrix(), xlsread(), etc. to read in your data file.
