SinhIntegral[z] gives the hyperbolic sine integral function Shi(z).

TransferFunctionZeros[tf] gives a matrix of roots of the numerators in the TransferFunctionModel object tf.

ZTransform[expr, n, z] gives the Z transform of expr. ZTransform[expr, {n_1, n_2, ...}, {z_1, z_2, ...}] gives the multidimensional Z transform of expr.

When you do calculations with arbitrary-precision numbers, Mathematica keeps track of precision at all points. In general, Mathematica tries to give you results which have ...

When Mathematica plots a graph for you, it has to make many choices. It has to work out what the scales should be, where the function should be sampled, how the axes should ...

Often a web service requires using data other than a simple string. This data could be something simple like an integer or a real. Often the data is more complex and is a ...

NProduct[f, {i, i_min, i_max}] gives a numerical approximation to the product \[Product]i = i_min i_max f.NProduct[f, {i, i_min, i_max, di}] uses a step di in the product.

LeastSquares[m, b] finds an x that solves the linear least-squares problem for the matrix equation m.x == b.
