[Scilab-users] Hypermatrix manipulation

[Rafael Guerra]

Hello,
 
Here below a more inefficient solution but that might fit your needs:
 
// Hypermatrix definition M(x,y,z,k)
x=[1 1.5 2]; y=[0 1 %e %pi]; z=[2 3].^0.5; k=1:5;
nx=length(x); ny=length(y); nz=length(z); nk=length(k);
M=rand(nx,ny,nz,nk);
 
// Write coordinates and M to disk:
fid = mopen("hyper_out.txt",'w');
for i=1:nx; for j=1:ny; for m=1:nz; for n=1:nk
 
mfprintf(fid,"%15.5f%15.5f%15.5f%15.5f%15.5f\n",x(i),y(j),z(m),k(n),M(i,j,m,n));
end; end; end; end
mclose(fid)
 
 
Regards,
Rafael

I do not know Gambit nor Pointwiseinput format,  but you can transform 
your hypermatrix to a 1D array using v=M(:) then write the vector and 
the dimensions in an ascii file using the mfprintf function....
 
Nb V=[M(1,1,1,1);M(2,1,1,1);...M(1,2,1,1);M(2,2,1,1);... M(1,1,2,1);....]
