24 ## WARNING: Unlike the C function of the same name, this function |
|
|
25 ## returns 1 for equal and zero for not equal. Why? To be compatible |
|
|
26 ## with Matlab, of course. |
|
|
27 ## |
|
|
28 ## Why doesn't this always return a scalar instead of vector with |
|
|
29 ## elements corresponding to the rows of the string array? To be |
|
|
30 ## compatible with Matlab, of course. |
