Dear all,

As the subject line suggests, fortran95 interface of dsyevr, namely, syevr returns -1001 as info parameter. I could not understand what this means, could you please help me with this problem?

Best regards,

Umut

The value returned indicates a botched call, probably caused by not providing an interface or because of errors in the arguments to the routine. You will need to provide a complete example source code in order for us to identify the precise error.
