latexifier 1.0.2

A package to convert python objects into latex strings

latexify

Install with pip install latexifier

Use with from latexifier import latexify

This module aims to turn python objects into latex strings. For instance:

• Integers: latexify(20) returns "20"
• Python Fractions: latexify(Fraction(1,3)) returns "\frac{1}{3}"
• Approximate Fractions: latexify(0.25) returns "\frac{1}{4}"
• Approximate combination of radicals: latexify(0.5 - 3 * numpy.sqrt(5)) returns "\frac{1}{2} - 3\sqrt{5}"
• Complex numbers: latexify(numpy.sqrt(2) + 3.5j) returns "\sqrt{2}+\frac{7}{2}i"
• numpy.arrays: latexify(numpy.eye(2)) returns "\begin{pmatrix} 1&0\\0&1 \end{pmatrix}"
• tuples: latexify((1,2,3)) returns "\left(1,2,3\right)"
• lists: latexify([1,2,3]) returns "1,2,3"
• sympy polynomials: latexify(x**2 - y*z/3) returns "x^2 - \frac{yz}{3}"
• All those objects can be combined and nested: list of arrays, arrays of polynomials, etc.

When given integer-based values (such as Integers or Fractions), latexify returns a string without any ambiguity. When given a float, latexify tries to approximate this float by means of fractions and radicals. To so, the search is limited to "small" fractions and "small" radicals. This behavior can be changed with the function latexifier.parameters(parameter_name=parameter_value). Here are a few important ones:

• denominator_max (default: 10). Maximal denominator allowed in fractions
• radical_max (defaut: 7). We allow for sqrt(n) to show up, with n <= radical_max
• frmt (default: '{:3.6f}'). format for rounding reals when no nice approximation is found
