When calling the matlabpool to work in parallel, does each worker work in single-thread mode?

Hi, when I call a matlabpool of workers, and each worker has to compute a routine which is optimized by the BLAS subroutines (e.g., the backslash operator), will each workers exploit the multi-thread mode or since I have called the matlabpool each of them will work in single-thread mode? (I assume the multi-thread mode is available for default when lunching MATLAB). Thanks

Workers are started up in single-thread mode in order to avoid over-subscribing the machine and negatively impacting performance. Backslash would indeed be affected by this since it is multi-threaded by default when launching MATLAB.
