Generalised uncorrelated Wishart matrices are formed out of rectangular standard
Gaussian data matrices with a certain pattern of zero entries. Development of the
theory in the real and complex cases has proceeded along separate lines. For example,
emphasis in the real case has been placed on the Bellman and Riesz distributions,
while the complex case has been shown to be closely related to the Muttalib–Borodin
model. In this work, as well as uniting the lines of development, a tie-in
with matrix spherical functions is identified in the context of deducing the
eigenvalue probability density function from the joint element probability density
function.
