Syntax

chr = mathml(f)
chr = mathml(f,Name,Value)

Description

example

chr= mathml（f)returns the generated MathML from the symbolic expressionf.

example

chr= mathml（f,Name,Value)uses additional options specified by one or more name-value pair arguments. For example, generate MathML for inline display by specifyingDisplayInlineas真正.

Examples
