MathML and fractions
-
The are a few ways you can generate typeset maths. Below are a number of options that you can try when generating expressions. They behave slightly differently to each other but I include them here for discussion.
$a1=maple("x^(5/2)"); #temporarily assign to variable inside maple call $d1=maple("a1:=$a1:printf(MathML[ExportPresentation](a1))"); #whole calculation done in maple call $d2=maple("a1:=x^(5/2):printf(MathML[ExportPresentation](a1))"); # using codegen $a3=maple("x^(5/2)"); $d3=maple("codegen[MathML]($a1)"); #using just Export $a4=maple("x^(5/2)"); $d4=maple("printf(MathML[Export]($a1))"); # if you prefer the 5/2 form $a5=maple("x^(5/2)"); $d5=maple("printf(MathML[ExportPresentation]($a1))");
Here is the output they generate. Notice that $d1 to $d4 give the same result, but $d5 is different. Under the hood the first 4 are generating fractions using the MathML <mfrac> whereas $d5 is using <mrow>.
