<loop clause>::= while <logical expression> do <series> od
Evaluate logical expression, if non-zero execute series and repeat.
Example:
a=[1,3,7,5]; i=1; while (i<=size(a) && a[i] != 7) do i=i+1 od; i
result: 3
@&&(int,int)
<logical_expression>::= <expression> && <expression>
Logical AND operator, lazy in its right operand.
First the left operand is evaluated. If it returns 0 (false) evaluation
stops returning 0, otherwise the right operand is evaluated; if it is
non-zero, 1 is returned, otherwise 0.
@||(int,int)
<logical_expression>::= <expression> || <expression>
Logical OR operator, lazy in its right operand.
First the left operand is evaluated. If it is non-zero (true) evaluation
stops returning 1, otherwise the right operand is evaluated; if it is
non-zero, 1 is returned, otherwise 0.
@return()lieshell
<statement>::= return
| return <expression>
Terminates the current function, returning the value of the expression,
if present, and void otherwise.
@/(pol,int)
p/n
Returns the polynomial with the coefficients of p divided by n.
Examples 6X[8]/2 = 3X[8]; 11X[30,4]/3 = 3X[30,4]
@/(pol,vec)
p/v
Returns the polynomial with the exponents of p divided position-wise by
the entries of v.
Examples 6X[8]/[2] = 6X[4]; 11X[30,4]/[6,2] = 11X[5,2]
divided by a.
@*(pol,int)
p*n
Returns the polynomial with all exponents of p multiplied by n.
Example 3X[5,2]*4 = 3X[20,8]
@*(int,pol)
n*p
Returns the polynomial with the coefficients of p multiplied by n.
Example 4*3X[5,2] = 12X[5,2]
@*(pol,mat)
p*m
Returns the polynomial with all exponents of p multiplied to the right by m.
Example 3X[5,2]*[[0,1],[3,0]] = 3X[6,5]
@pol()silence
Type indication for polynomials. See 'polynomial'.
@|(pol,vec)
p|v
Searches in polynomial p the term with exponent v and returns its coefficient
(0 if term is not present).
Example (2X[1,2]+5X[8,7])|[8,7] = 5
p|v = n
Changes the coefficien of the term with exponent v in polynomial p into n
(if necessary a term is created).
Example p=1X[0,0]; p|[1,2]=7 results in p = 1X[0,0]+7*X[1,2]
@+=(bin,bin)
a+=b replaces a by a+b.
a[i]+=b replaces a[i] by a[i]+b.
a[i,j]+=b replaces a[i,j] by a[i,j]+b.
@+=(vec,int)
a+=b appends integer b as final entry to vector a and stores the result in a.
@+=(mat,vec)
a+=b appends vector b as final row to matrix a and stores the result in a.
@+=(tex,bin)
a+=b appends text for integer b to string a and stores the result in a.
@+=(tex,tex)
a+=b appends string b to string a and stores the result in a.
@fmt(bin,int)lieshell
fmt(d,w) converts the integer d into a string of width at least w.
if w < 0 then the output is left adjusted.
if w > 0 then the output is right adjusted.
@support(pol)polynomials
support(p). Returns the matrix whose rows are the exponents of p.
@polynom(mat)polynomials
polynom(m). Returns the polynomial with coefficients 1 and with as
exponents the rows of m. This is the same as `X m'.
@row_index(mat,vec,int,int)array
row_index(m,v,lb,ub) Searches for i=lb, ..., ub whether m[i]==v.
The first such i is returned, or 0 if none was found.
@maxobjects()lieshell
maxobjects N Sets the maximum number of objects to N. The value N should
be large enough to hold all objects of the computation (where each polynomial
coefficient counts as separate object), but excessively large N could postpone
garbage collection to the point that physical memory gets depleted.
@maxnodes()lieshell
maxnodes N sets the maximum number of nodes (for storing programs) to N.
@listvars()lieshell
listvars generates a list of the variabes defined in this session of LiE.
@listfuns()lieshell
listfuns generates a list of the functions defined in this session of LiE.
