Matrix Feedback - mkraska/meclib GitHub Wiki

Input

Field	Value
Input type	Matrix
Model answer	Matrix variable

Potential response tree for symbolic answers

Field	Value
Format	Compact
Answer test	AlgEqiv
SAns	`S_<name>`
TAns	`<name>`

You can apply fb_vars to the individual components. Provide labels to specify to which component the feedback applies.

{@fb_vars(S_RF[1,1], RF[1,1], [], "\\(x\\):")@}
{@fb_vars(S_RF[2,1], RF[2,1], [], "<br>\\(y\\):")@}
{@fb_vars(S_RF[3,1], RF[3,1], [q,F_1], "<br>\\(z\\):")@}

Potential response tree for numeric answers

Field	Value
Feedback variables	`toList(m):= args(transpose(m))[1];`
Format	Compact
Answer test	NumRelative
SAns	`toList(S_<name>)`
TAns	`toList(<name>)`
Quiet	`Yes` (optional, if you provide feedback to the components on your own as shown below)

You can apply fb_unit to the individual components. Provide labels to specify to which component the feedback applies.

Column vector A

<br>\(x\): {@fb_unit(S_A[1,1], A[1,1], 0.005)@}
<br>\(y\): {@fb_unit(S_A[2,1], A[2,1], 0.005)@}
<br>\(z\): {@fb_unit(S_A[3,1], A[3,1], 0.005)@}

Row vector F

<br>\(N\): {@fb_unit(S_F[1,1], F[1,1], 0.005)@}
<br>\(Q_y\): {@fb_unit(S_F[1,2], F[1,2], 0.005)@}
<br>\(Q_z\): {@fb_unit(S_F[1,3], F[1,3], 0.005)@}
