InverseRadon[image] gives the inverse discrete Radon transform of image.InverseRadon[image, {w, h}] specifies the width w and the height h of the resulting image.
MatrixQ
(Built-in Mathematica Symbol) MatrixQ[expr] gives True if expr is a list of lists or a two-dimensional SparseArray object that can represent a matrix, and gives False otherwise. MatrixQ[expr, test] gives ...

SymmetricGroup[n] represents the symmetric group of degree n.
There are many detailed differences between different kinds of computer systems. But one of the important features of Mathematica is that it allows you to work and create ...
Basic vector operations. This is a vector in three dimensions. This gives a vector u in the direction opposite to v with twice the magnitude.
You can think of an expression like f[x] as being formed by applying an operator f to the expression x. You can think of an expression like f[g[x]] as the result of composing ...
