I have attached a picture to what I mean by this error. Any help would be appreciated on how I could overcome this error. This is usually how i code using the matlab coder but i think the matlab function in simulink doesn't accept a lot of syntax.
Thanks!

Remove the word end from brackets

Whats the difference between indexing the last value of an array and creating a new variable with just the last value of the array and using it for comparison? I managed to get past that error by using this in the mean time.
if PCMTemp < SampleTemperatureHeating(length(SampleTemperatureHeating))

SampleTemperatureHeating(length(SampleTemperatureHeating))
When you use length(yourarray) it gives largest value of array dimension. This means maximum number of elements in array. If you use in parenthesis () matlab will return the last value in that array. But this is usually not recommended as when your code gets larger, it becomes difficult to debug at later stage. That's why assign it to variable and call that variable inside the array.
K = length(SampleTemperatureHeating)
SampleTemperatureHeating(K)

It looks to me like the problem in that screenshot is a typo: "Heaating" vs. "Heating" in the variable name which you are trying to index with (end).

I fixed that typo and ended up still getting that error. I found a way around it. I just used this lol
if PCMTemp < SampleTemperatureHeating(length(SampleTemperatureHeating))
