If you're just multiplying by the scaler of 1.02 then
Qxxepoch1{:,:}*1.02
will do what you want without a loop

Just to expand on the information above - your original data was stored in a table. You can't apply the times (*) operator directly on the table, so writing
Qxxepoch1{:,:}
extracts all the data in the table into a matrix. Holding the data in a matrix allows you to apply the times operator to multiply the elements by 1.02. However, as mentioned above, to access the data in a matrix you use the normal indexing with parenthesis () - using brace {} indexing on a matrix will cause the error you experienced. It can be confusing - you just need to be aware of what your data is stored in, and use the appropriate indexing for the task.
