perl - Eliminate intermediate variable when combining here document, substitution and die -


is possible eliminate use of intermediate variable $msg in example?

($msg = <<'end_msg') =~ s/\n//gm; super error message happens span on multiple lines want print without newlines. end_msg die $msg;

if did not need remove newlines, directly die <<'end_msg'; ... have not found way combine these 2 approaches.

with perl 5.14 or newer can,

die <<'end_msg' super error message happens span on multiple lines want print without newlines. end_msg =~ s/\n//gr;

edit: or

die <<'end_msg' =~ s/\n//gr .. end_msg

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
