How can I model a temperature change using MATLAB?

[BubblesAreUs]

Homework Statement

Modelling the following equation:

k = Delta Q / t

Homework Equations

Q = T2 - T1 = -40 (fixed)

t = Delta Q / k. I need to find t.

k can be floating so I suppose 0 to 10 minutes with 0.5 increments

The Attempt at a Solution

I don't have MATLAB on me at the moment, but I think I should just set a loop for k, nest the expression for t and the plot a k vs t curve.

Does that sound right?

Is the delta Q a fixed constant or does it depend on k or t?

Delta Q is a fixed variable and rather k, t depend on it as they are floating variables.

MATLAB is a bit different from python in that its arrays aren't indexable. Say x = [1,2,3,4,5], I can't use x[0] = 1, x[3] = 4, etc.

MATLAB arrays are indexable. I've used array indexing in for loops and it works quite well although its not vectorized and hence runs a bit slower.

You need to x(0) not x[0] as shown in your post.
