SymmetricMatrixQ[m] tests whether m is a symmetric matrix.

x*y*z, x*y*z, or x y z represents a product of terms.

Tr[list] finds the trace of the matrix or tensor list. Tr[list, f] finds a generalized trace, combining terms with f instead of Plus. Tr[list, f, n] goes down to level n in ...

UpperTriangularize[m] gives a matrix in which all but the upper triangular elements of m are replaced with zeros. UpperTriangularize[m, k] replaces with zeros only the ...

Some basic matrix operations. Transposing a matrix interchanges the rows and columns in the matrix. If you transpose an m×n matrix, you get an n×m matrix as the result. ...

Functions for constructing matrices. This generates a 2×2 matrix whose i,j^th entry is a[i,j]. Here is another way to produce the same matrix.

CUDAArgMinList[list] gives the index of the minimum element in list.

CUDAInverseFourier[list] finds the discrete inverse Fourier transform of a list of complex numbers.CUDAInverseFourier[mem] finds the discrete inverse Fourier transform of a ...

Plot[f, {x, x_min, x_max}] generates a plot of f as a function of x from x_min to x_max. Plot[{f_1, f_2, ...}, {x, x_min, x_max}] plots several functions f_i.

HistogramDistribution[{x_1, x_2, ...}] represents the probability distribution corresponding to a histogram of the data values x_i.HistogramDistribution[{{x_1, y_1, ...}, ...
