 # Python | The numpy np.hermsub () method

With the `np.hermsub() ` method we can subtract one row of hermites into another using ` np.hermsub () `.

Syntax: ` np.hermsub (series1, series2) `
Return: Return the coefficients after subtraction of series.

Example # 1:
In this example, we see that with ` np.hermsub () ` we can get the subtraction of two Hermite rows with this method.

 ` # numpy and hermsub imports ` ` import ` ` numpy as np ` ` from ` ` numpy.polynomial.hermite ` ` import ` ` hermsub ` ` `  ` series1 = np.array ([ 1 , 2 , 3 , 4 , 5 ]) ```` series2 = np.array ([ 6 , 7 , 8 , 9 , 10 ])   # using the np.hermsub () method gfg = hermsub (series1, series2)    print (gfg) ```

Output:

[-5. -five. -five. -five. -5.]

Example # 2:

` `

``` # numpy and hermsub imports import numpy as np from numpy.polynomial.hermite import hermsub   series1 = np.array ([ 1 , 0 , 3 , 0 , 5 ]) series2 = np .array ([ 0 , 7 , 0 , 9 , 0 ])   # using the np.hermsub () method gfg = hermsub (series1, series2)   print (gfg) ```

` `

Output:

[1. -7. 3. -9. 5.]
