You probably mean "evstr". As far as I understand Matlab's function, no. 
It makes repeated calls to the sscanf function, until something works. 
The process stops when one scan works. If no scan works, this is an 
error. This is probably not as fast as possible. I do not know if using 
regexps to do this is easy within a compiled source code. I will suggest 
Allan to see this topic.
