profile
extract execution profiles of a Scilab function
Calling Sequence
c=profile(fun)
Arguments
- fun
a Scilab function
- c
a nx3 matrix containig the execution profiles
Description
To use profile
the Scilab function must have been prepared for
profiling (see exec).
For such function, When such a function is executed the systems counts
how many time each line is executed and how may cpu time is spend for
each line execution. These data are stored within the function data
structure. The profile function allows to extract these data and
return them in the two first columns of c
. The c
third
column gives a measure of interpetor effort for one execution of
corresponding line. Ith line of c
corresponds to Ith line of the
function (included first)
Note that, due to the precision of the processor clock (typically one micro second), some executed lignes may appear with 0 cpu time even if total cpu time really spend in their execution is large.
Examples
//define function and prepare it for profiling deff('x=foo(n)',['if n==0 then' ' x=[]' 'else' ' x=0' ' for k=1:n' ' s=svd(rand(n+10,n+10))' ' x=x+s(1)' ' end' 'end'],'p') //call the function foo(10) //get execution profiles profile(foo) //call the function foo(20) profile(foo) //execution profiles are cumulated
