Statement Overview
To explicitly free (almost) the entirety of the memory used by a vector that is no longer needed,
in the case that it is needed to do so before the task or function terminates, use:
free (b)
The free command frees the entire vector, whatever the number of dimensions.
Vector Attributes
A set of useful attributes is available on vectors:
• imin to get the minimum index of the vector
• imax to get the maximum index of the vector
• size to get the size of the vector
Example:
set a[0,10] = 1
fprint(stdout, "a.imin = %d\n", a.imin)
fprint(stdout, "a.imax = %d\n", a.imax)
fprint(stdout, "a.size = %d\n", a.size)
Passing Vectors as Task Arguments
Example using a vector as an input argument:
.define_task my_vector_average (a[]=0, @avg=0)
set tmp=0 i=0
step (type=linear, param=i, start=a.imin, stop=a.imax, step=1)
tmp = tmp + a[i]
endstep
avg = tmp / a.size
.end_define_task
The corresponding call from another task would be:
set tprop[0,99]=0 tprop_avg=0
my_vector_average (a=tprop, tprop_avg=@avg)
Example using a vector as an output argument:
830
