They are all spelled with two tokens followed by one zero.
The first token of the name is tVarMat, which labels it as a matrix variable name. The
second token signifies which predefined matrix name it is, [A] – [J].

Equation Variables: Y1 – Y0, X1t – X6t, Y1t – X1t, r1 – r6, u(n), v(n), w(n)
These variables can be type EquObj or NewEquObj.
They are all spelled with two tokens followed by one zero.
The first token of the name is tVarEqu, which labels it as an equation variable name.
The second token signifies which predefined equation name it is:
tY1 – tY0 for Y1 – Y0
tX1T – tX6T for X1t – X6t
tY1T – tY6T for Y1t – Y6t
tR1 – tR6 for r1 – r6
tun for u(n)
tvn for v(n)
twn for W(n)
