Explanation:
You are attempting to concatenate two arrays using [] but the appropriate dimensions along which to concatenate are not the same size.
Common causes:
You have forgotten a semicolon (;) or a comma (,) when attempting to concatenate two character arrays, or you are using the wrong separator. This error commonly occurs when attempting to concatenate character arrays to try to create a multi-line string.
Solution:
Examine the line listed in the error message and insert the appropriate matrix element separator. Also verify that the dimensions along which you are trying to concatenate the matrices agree. The help files for the HORZCAT and VERTCAT functions describe the relationship that needs to exist for this concatenation to work correctly.
horzcat(A,B)
is the equivalent of [A B] while
vertcat(A,B)
is the equivalent of [A;B]. If you are attempting to concatenate strings, you should use the STRCAT and STRVCAT functions, which handle adjusting the appropriate dimensions automatically if it is necessary.
Example demonstrating this error:
