How do I replace one value of a matrix with another value from a different matrix?

How to you swap a variable in one matrix with another variable from a different matrix without typeing in (for example) E(1,2) = 3?
Is there a way to do it by specifying the matrix and the values position that you want to use to swap?
I have tried to say something like A(1,1)=B(2,2) but I keep getting this error:
Incorrect use of '=' operator. Assign a value to a variable using '=' and compare values for equality using '=='.

It will work but you're going to have to type something after the equals sign, like
A(1,1) = B(2,2)
otherwise how will it know the location in B and the location in A?
Show the entire actual error message, not just a snippet from it. Specifically the error message will show the line of code and you forgot to include that. Show us ALL THE RED TEXT.
It's possible you had an "if" before that. Or it's possible that B is not the same class as A. What does this show?
whos A
whos B
A(1,1) = B(2,2)

I don't find any issue.please attach your data and code.
A=[3 6 8 9;1 2 5 6]
A = 2×4
3 6 8 9 1 2 5 6
B=[11 22 33 44;55 66 77 88];
A = 2×4
66 6 8 9 1 2 5 6
