R2007b

19-20

Existing program code that relies on the colon operations of character arrays returning a

double, needs to be updated to expect a character data type.

Matrix Generating Functions No Longer Accept Complex Inputs

Calling matrix generating functions, such as ones, zeros, rand, randn, true, and

false, with a complex number as dimensions input now returns the error:

true([1 i])

??? Error using ==> true

Size vector must be a row vector with real elements.

Compatibility Considerations

In previous releases, if you supplied a complex number as a dimension input, MATLAB

software returned:

true([1 i])

Warning: Size vector should be a row vector with integer elements.

Complex inputs will cause an error in a future release.

ans =

Empty matrix: 1-by-0

Existing program code that relies on entering complex numbers as dimension input to a

matrix generating function should be modified.
