This function allows to call a computational function from a Scicos block
structure. The fields of that structure must be properly informed before use it with callblk.
A simplified flowchart of how work callblk is shown in the following figure:
From the input structure blk_in, a C scicos_blocks structure is allocated and informed, the pointer
of the comptational function is found, and the computational function is then called with the C structure
and the parameter flag. Finally an output scilab structure blk_out is created with the values
contained in the C structure.
callblk can be used to do prototypes of code generator and simulator in Scilab language.
[blk]=callblk(blk,flag,time)

omod=scs_m.objs(10).model; //scope is the obj(10)
omod.in=1; //update in (because -1)

for i=0:1:Tfin*100
t=i/100;
//update regular input
bl.inptr(1)=0.55+cos(2*%pi/(15)*t)/10;
bl=callblk(bl,2,t); //calblk with flag=2
end
// finish
bl=callblk(bl,5,t);
