Within array initializations, when a line ends with a comma, rather than an ellipsis line continuation indicator (...), MATLAB ignores the comma and the new line takes precedence. Thus, MATLAB interprets a new line as a new row. Your use of a comma suggests that you are trying to create a row vector, rather than a column vector. This might not matter because row and column vectors work the same way in many situations.

To specify a row vector, insert an ellipsis (...) after the comma at the end of the row. To specify a column vector, remove the comma or replace it with a semicolon, so that your intentions are clear. If you prefer to leave your code as is, then suppress the message or turn it off in the preferences panel, as described in Adjust Code Analyzer Message Indicators and Messages.
