> (greater than)
expr1 > expr2
list1 > list2
matrix1 > matrix2
Return True if first argument can be determined
to be greater than the second argument. Return
False if first argument can be determined to be
less than or equal to the second argument.
Otherwise, return a simplified form of the
comparison. For list and matrix arguments,
return element-by-element comparisons.
≥
≥≥
≥ (greater than or equal to)
expr1 ≥ expr2
list1 ≥ list2
matrix1 ≥ matrix2
Return True if first argument can be determined
to be greater than or equal to the second
argument. Return False if first argument can be
determined to be less than the second
argument. Otherwise, return a simplified form of
the comparison. For list and matrix arguments,
return element-by-element comparisons.
.+ (dot add)
matrix1 .+ matrix2
Return matrix whose elements are the sums of
the corresponding elements of matrix1 and
matrix2.
expr .+ matrix
matrix .+ expr
Return matrix whose elements are the sums of
expr and matrix.
.- (dot subtract)
matrix1 .- matrix2
Return matrix whose elements are the
corresponding elements of matrix2 subtracted
from matrix1.
expr .- matrix
Return matrix whose elements are the
elements of matrix subtracted from expr.
matrix .- expr
Return matrix whose elements are expr
subtracted from the elements of matrix.
.* (dot multiply)
matrix1 .* matrix2
Return matrix whose elements are the products
of each corresponding elements of matrix1 and
matrix2.
expr .* matrix
matrix .* expr
Return matrix whose elements are the product
of expr and the elements of matrix.
./ (dot divide)
matrix1 .* matrix2
Return matrix whose elements are the quotients
of the corresponding elements of matrix1
divided by matrix2.
expr .* matrix
matrix .* expr
Return matrix whose elements are the quotients
of expr divided by the elements of matrix, or the
elements of matrix divided by expr.
.^ (dot power)
matrix1 .^ matrix2
Return matrix whose elements are the elements
of matrix1 raised to the power of the
corresponding matrix2 elements.
expr .^ matrix
matrix .^ expr
Return matrix whose elements are expr raised
to the power of each matrix element, or the
elements of matrix raised to the expr power.
! (factorial)
expr!
list!
matrix!
Return the factorial of the argument. Only
returns a numeric value for non-negative integer
arguments.
& (append)
string1 & string2
Return string which is string2 appended to
string1.
·
··
·() (integrate)
(expr,var[,lower][,upper])
(list,var[,lower][,upper])
(matrix,var[,lower][,upper])
Return the integral of the first argument with
respect to var, from lower to upper integration
limits. Return anti-derivative if lower and upper
are omitted; constant of integration is omitted,
but lower will be added as a constant of
integration if upper is not used. Anti-derivatives
may differ by a numeric constant. Piece-wise
