integral function gives error

R = 8.3145;
rxnH1500 = deltaHrxn + integral(deltaCpfxn, 298, 1500)
KaIntegralFunc = @(T) rxnH1500/(R*(T^2))
integral(KaIntegralFunc, 0, 1)

Running this code gives a long error message with

----

"Error using ^

One argument must be a square matrix and the other must be a scalar. Use POWER (.^) for elementwise power.

Error in cheg325hw8q2>@(T)rxnH1500/(R*(T^2))

I don't understand why the integral didn't work, as the function works just fine.

do not see the function that is being integrated anywhere in your Question. However the error message tells you exactly what to do:

Use POWER (.^) for elementwise power.
