Made LinearOperator independent of spLinearOperator

[rohanbabbar04]

For issue #328

• Added _AdjointLinearOperator, _TransposeLinearOperator and _ProductLinearOperator
• Added methods __matmul__,__rmatmul__ , transpose and adjoint
• Made all classes extend the LinearOperator

Still need to change/update the docs, if code seems fine...

Thank you!

I'll try to review this in coming days and let you know :)

Will do soon :)

I just identified a problem with describe due to some of the internal linop methods being moved from scipy to native pylops ones...

For example:

A = pylops.MatrixMult(np.ones((10, 5)))
A.name = "A"
C = pylops.MatrixMult(np.ones((10, 5)))

# Sum
D = A + C
describe(D)

now returns A where: {'A': '_SumLinearOperator'} instead of A+M where: {'A': 'MatrixMult', 'M': 'MatrixMult'}.

Currently investigating why...

[rohanbabbar04]

Is the bug fixed?

[rohanbabbar04]

Just tested the code Now the describe works fine

A + M
where: {'A': 'MatrixMult', 'M': 'MatrixMult'}

A + M
where: {'A': 'MatrixMult', 'M': 'MatrixMult'}

So I am removing the docstrings to make the Codacy Static Code Analysis successful Removing this and making a commit

[mrava87]

Yes the code is fixed :)

[rohanbabbar04]

Yes the code is fixed :)

@mrava87 Made the commit all checks are now successful...

[mrava87]

@rohanbabbar04 I am satisfied with the current status of the PR.

Since we are making changes to a core method of PyLops, I want to get the feedback of another core developer before merging.. please be patient, we will let you know soon when this is ready to go :)

I'll be trying this patch very soon! Sorry for the delays!
