Energy required to heat water at constant pressure is approximately :
E=m * Cp(delta T)
m=mass
Cp= heat capacity of H2O 1cal/gK
delta T= change in temperature
Create an anonymous function called heat to find energy required to heat 1 gram of H2O if change in temp is provided as the input
g [(cal 1)/(g K)] K = cal
Joules are the units of energy used most often. Create another anonymous function cal_to_J to convert your answer to Joules (4.2 J/ cal)
Save your anonymous function to a .mat file.
This is what I have so far:
heat=@(g,T) g.*T;
heat
heat(1,T)
cal_to_J=@(ans) ans.*4.2
cal_to_J
cal_to_J(ans)
Any help would be appreciated, thank you!!

I think it is because you defined your function as t but typed T in your formula

The poster never used "t". The poster did, though, try to call heat(1,T) in a context where T is not defined
