Will something along the following lines work?:

a=randn(10,5);
fp=fopen("mat.h", "w");
fprintf(fp, "double *mat={ ");
for i=1:size(a,1)
   fprintf(fp, "{ %f", a(i,1));
   for j=2:size(a,2)
      fprintf(fp,", %f", a(i,j));
   endfor;
   fprintf(fp, "},\n");
endfor;
fprintf(fp, "};\n");
fclose(fp);
