to_latex

The method uses named parameter passing style. Valid parameters are:

implicit_multiplication

Used to turn on the '.' ("\cdot") operators for all multiplications. Defaults to true, that is, the multiplication operators are not present.

no_fractions

Use '/' division operator instead of fractions. Defaults to false, that is, use fractions. See also: "max_fractions" parameter.

max_fractions

Setting this parameter to a positive integer results in a limitation of the number of nested fractions. It defaults to 2. Setting this to 0 results in arbitrarily nested fractions. To disable fractions altogether, set the "no_fraction" parameter.

exclude_signature

By default, the method includes all variables' signatures in parenthesis if present. Set this to true to omit variable signatures.

replace_default_greek

By default, all variable names are outputted as LaTeX in a way that makes them show up exactly as they did in your code. If you set this option to true, Math::Symbolic will try to replace as many greek character names with the appropriates symbols as possible.

Valid LaTeX symbols that are matched are:

  Lower case letters:
    alpha, beta, gamma, delta, epsilon, zeta, eta, theta,
    iota, kappa, lambda, mu, nu, xi, pi, rho, sigma,
    tau, upsilon, phi, chi, psi, omega
  
  Variant forms of small letters:
    varepsilon, vartheta, varpi, varrho, varsigma, varphi
  
  Upper case letters:
    Gamma, Delta, Theta, Lambda, Xi, Pi, Sigma, Upsilon, Phi,
    Psi, Omega
    

variable_mappings

Because not all variable names come out as you might want them to, you may use the 'variable_mappings' option to replace variable names in the output LaTeX stream with custom LaTeX. For example, the variable x_i should probably indicate an 'x' with a subscripted i. The argument to variable_mappings needs to be a hash reference which contains variable name / LaTeX mapping pairs.

If a variable is replaced in the above fashion, other options that modify the outcome of the conversion of variable names to LaTeX are ignored.

subscript

Set this option to a true value to have all underscores in variable names interpreted as subscripts. Once an underscore is encountered, the rest of the variable name is treated as subscripted. If multiple underscores are found, this mechanism works recursively.

Defaults to "true". Set to a false value to turn this off. This is automatically turned off for variables that are mapped to custom LaTeX by the "variable_mappings" parameter.

no_sqrt

By default, the dumper tries to convert exponents of 1/2 (or 0.5) or anything numeric that ends up being 1/2 to a square root. If this gives inconvenient results, set this option to a true value to turn the heuristics off.
