algebra

I've come across a weird behavior that really baffled me initially.

This compiles with nalgebra 0.29:

let _: nalgebra::SVector<f32, 3> = nalgebra::point![1.0, 2.0].into();

It converts an OPoint<f32, 2> into an SVector<f32, 3>, using Into.

Here's the same, with debug output:

let v: nalgebra::SVector<f32, 3> = dbg!(nalgebra::point![1.0, 2.0]).into();
dbg!(v

Right now we have code like this for "URL" based help viewers:

    HELP_VIEWER_INFO.firefox := rec(
    type := "url",
    show := function(url)
      Exec(Concatenation("firefox \"file://", url,"\" >/dev/null 2>&1 &"));
    end
    );

So clearly the "URL" they get isn't a real URL, it's just a path (plus possibly an anchor, so foo.html#123). This should be refactored: the ca

Plot.polar would take p(phi), e. g.

Plot.polar [ (parsed 0.0)..(parsed 0.01)..(pi / 2) ] "phi + cos(phi)"

So far a single damping factor (epsR and epsI) can be provided to pylops.avo.prestack.PrestackInversion. However as it is known that some parameters are more constrained than others in any AVO linearisation it is useful to provide different damping factors for the different parameters to invert for.

Someone interested in improving the Symja help/tutorial?
