Display the expression.

showexpr(expr)

  8*x(1, 1) + 3*x(2, 1) + 4*x(3, 1) + x(1, 2) + 5*x(2, 2) + 9*x(3, 2) + 6*x(1, 3) + 7*x(2, 3) + 2*x(3, 3)

Input Arguments

expr — Optimization expression

OptimizationExpression object

Optimization expression, specified as an OptimizationExpression object.

Tips

• For an expression that has many terms, use writeexpr to generate a text file containing the expression information.

Version History

Introduced in R2017b

R2019b: showexpr is not recommended

The showexpr function is not recommended. Instead, use show. The show function replaces showexpr and many other problem-based functions.

There are no plans to remove showexpr at this time.
