8.2.59.68 table.evalWithVars

Method: out = evalWithVars (obj, expr)

Evaluate an expression against table’s variables.

Evaluates the M-code expression expr in a workspace where all of obj’s variables have been assigned to workspace variables.

expr is a charvec containing an Octave expression.

As an implementation detail, the workspace will also contain some variables that are prefixed and suffixed with "__". So try to avoid those in your table variable names.

Returns the result of the evaluation.

Examples:

[s,p,sp] = table_examples.SpDb
tmp = join (sp, p);
shipment_weight = evalWithVars (tmp, "Qty .* Weight")
