In MATLAB, the multiplication is the asterisk ‘*’, not a dot ‘.’.

If you want to do element-wise operations, use the dot operator with the multiplication operator ‘.*’, and with other operators to do element-wise division and exponentiation. The other expression, ‘x.y’ will be interpreted as referring to a structure, and will throw a different error if that structure does not appear in your workspace.

See the documentation on Getting Started (link) to understand the essentials of MATLAB programming, and Array vs. Matrix Operations (link) to understand the ‘dot operator’.
