how could I create, say a 2x2, symbolic matrix using SymbolicUtils? e.g. something like [a11 a12; a21 a22] where aij are symbols… I cannot find in the manual… also, could I create a single symbol for a matrix e.g. m, and then access the element as a symbol like m[1,2] ? thanks.

Probably answers most of it: using ModelingToolkit @variables x a b r θ x + im * a x = r*cos(θ) + im*r*sin(θ) x.op # + x.args 2-element Array{Expression,1}: r * cos(θ) ((im) * r) * sin(θ) @shashi would have to answer the polynomial part.

This is very impressive!
