5.14. mul

Performs multiplication on the FitsArray object.

FitsArray.mul(self, other: Self | Fits | float | int | List[Fits | float | int], output: str | None = None) → Self

Performs multiplication on the FitsArray object.

Notes

This method can multiply numeric values, other Fits objects, or lists of numeric values or FitsArray objects.

  • If other is numeric, each element of the matrix will be multiplied by that number.

  • If other is another Fits object, element-wise multiplication will be performed.

  • If other is a list of numeric values, the first value will be applied to each matrix. The number of elements in the list must equal the number of elements in the FitsArray.

  • If other is another FitsArray, element-wise multiplication will be applied. The number of elements in both FitsArray objects must be equal.

Parameters

otherUnion[Self, Fits, float, int, List[Union[Fits, float, int]]]

Either a FitsArray object, list of floats, list of integers, Fits object, float, or integer.

outputOptional[str]

New path to save the files.

Returns

FitsArray

A new FitsArray object containing the saved FITS files.

Raises

NumberOfElementError

Raised when the length of other is incorrect.

5.14.1. Example:

from myraflib import FitsArray, Fits

fa = FitsArray.sample()
fa_2 = FitsArray.sample()

fits = Fits.sample()

multiplied_fa_1 = fa.mul(10)
multiplied_fa_2 = fa.mul(fits)
multiplied_fa_3 = fa.mul([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
multiplied_fa_4 = fa.mul([Fits.sample() for _ in range(10)])
multiplied_fa_5 = fa.mul(fa_2)

multiplied_fa_6 = fa * 10
multiplied_fa_7 = fa * fits
multiplied_fa_8 = fa * [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
multiplied_fa_9 = fa * [Fits.sample() for _ in range(10)]
multiplied_fa_10 = fa * fa_2
