I use gpbsv command from Intel MKL to solve symmetric positive band system. But unfortunately when the system is large I get an error Access violating writing location in VisualStudio.
Could someone give an advice how could I solve this system. Maybe I could use more optimized library? Maybe it's simplier to write my own solver for large problems ( where can I read about realizations ) ?
PS: I have only one notebook with Core i3.
