- Function:
*int***gsl_histogram2d_equal_bins_p***(const gsl_histogram2d **`h1`, const gsl_histogram2d *`h2`) This function returns 1 if all the individual bin ranges of the two histograms are identical, and 0 otherwise.

- Function:
*int***gsl_histogram2d_add***(gsl_histogram2d **`h1`, const gsl_histogram2d *`h2`) This function adds the contents of the bins in histogram

`h2`to the corresponding bins of histogram`h1`, i.e.*h'_1(i,j) = h_1(i,j) + h_2(i,j)*. The two histograms must have identical bin ranges.

- Function:
*int***gsl_histogram2d_sub***(gsl_histogram2d **`h1`, const gsl_histogram2d *`h2`) This function subtracts the contents of the bins in histogram

`h2`from the corresponding bins of histogram`h1`, i.e.*h'_1(i,j) = h_1(i,j) - h_2(i,j)*. The two histograms must have identical bin ranges.

- Function:
*int***gsl_histogram2d_mul***(gsl_histogram2d **`h1`, const gsl_histogram2d *`h2`) This function multiplies the contents of the bins of histogram

`h1`by the contents of the corresponding bins in histogram`h2`, i.e.*h'_1(i,j) = h_1(i,j) * h_2(i,j)*. The two histograms must have identical bin ranges.

- Function:
*int***gsl_histogram2d_div***(gsl_histogram2d **`h1`, const gsl_histogram2d *`h2`) This function divides the contents of the bins of histogram

`h1`by the contents of the corresponding bins in histogram`h2`, i.e.*h'_1(i,j) = h_1(i,j) / h_2(i,j)*. The two histograms must have identical bin ranges.

- Function:
*int***gsl_histogram2d_scale***(gsl_histogram2d **`h`, double`scale`) This function multiplies the contents of the bins of histogram

`h`by the constant`scale`, i.e.*h'_1(i,j) = h_1(i,j) scale*.

- Function:
*int***gsl_histogram2d_shift***(gsl_histogram2d **`h`, double`offset`) This function shifts the contents of the bins of histogram

`h`by the constant`offset`, i.e.*h'_1(i,j) = h_1(i,j) + offset*.
