Autolisp user function overloading -


you can read on autocad knowledge website:
"note: can define multiple user functions same name, have each definition accept different number or type of arguments."
has using feature? tried not work @ all. can call latest defined function.if call (file::appendfile arg1) autocad said give less argument
enter image description here

i'm not @ computer autocad installed, can't check if autolisp works way documentation says should, know i've seen workaround pass variable number of arguments function.

the trick pass arguments single list, , process list in body of function. example:

(defun myfunction (argslist / path header)   (setq path (car argslist))   (setq header (cadr argslist))   (somefunction path "a" header) )

... , you'd call function (myfunction '(arg1)) or (myfunction '(arg1 arg2)).

note in examples above i'm using list constructor literal, pass in actual strings "arg1" , "arg2". if want pass in contents of variables, you'd need use form (myfunction (list var1 var2)) instead.

it's little bit ugly, it's option.

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...
