|
|||
|
因本人没学过perl脚本，哪位能帮忙将下面一段代码转为perl脚本，谢谢！ #include #include main (argc, argv) int argc; char **argv; { float iq; int i, j, nbytes,ll; int nrig, nsamp; short *veti; float *vetf; char fi[100],fo[100]; FILE *ifp, *ofp; if (argc != 5) { printf ("usage: short2complex <#lines> <#samples> filein fileout\n"  ;exit(1); } sscanf (argv[1], "%i", &nrig); sscanf (argv[2], "%i", &nsamp); sscanf (argv[3], "%s", fi); sscanf (argv[4], "%s", fo); if(!(ifp=fopen(fi,"rb" )) {printf("Cannot open input file %s\n",fi); exit(1); } if(!(ofp=fopen(fo,"wb" )) {printf("Cannot open output file %s\n",fo); exit(1); } veti = (short *) malloc (2 * nsamp * sizeof (short)); vetf = (float *) malloc (2 * nsamp * sizeof (float)); for (i = 0; i < nrig; i++) { fread (veti, sizeof (short), 2 * nsamp, ifp ); for (j = 0; j < nsamp * 2; j++) { vetf[j] = (float) veti[j]; } fwrite (vetf, sizeof (float), 2 * nsamp, ofp); } fclose(ofp); fclose(ifp); } [ Last edited by 波不动 on 2010-1-13 at 20:48 ] |
