SizeMetrics-class {CVXR} | R Documentation |

## The SizeMetrics class.

### Description

This class contains various metrics regarding the problem size.

### Usage

SizeMetrics(problem)

### Arguments

### Slots

`num_scalar_variables`

The number of scalar variables in the problem.

`num_scalar_data`

The number of constants used across all matrices and vectors in the problem. Some constants are not apparent when the problem is constructed. For example, the `sum_squares`

expression is a wrapper for a `quad_over_lin`

expression with a constant `1`

in the denominator.

`num_scalar_eq_constr`

The number of scalar equality constraints in the problem.

`num_scalar_leq_constr`

The number of scalar inequality constraints in the problem.

`max_data_dimension`

The longest dimension of any data block constraint or parameter.

`max_big_small_squared`

The maximum value of (big)(small)^2 over all data blocks of the problem, where (big) is the larger dimension and (small) is the smaller dimension for each data block.
