`LinearStep`

## Purpose

sets up and solves the structure equilibrium equations for single load step

## Synopsis

`State = LinearStep (Model,ElemData,Loading)`

## Description

LINEARSTEP sets up and solves the structure equilibrium equations for single load step STATE = LINEARSTEP (MODEL,ELEMDATA,LOADING) function sets up and solves the structure equilibrium equations for single load step by direct assembly of element stiffness matrices; the structural response is contained in data structure STATE with fields U for the global dof displacement vector, Pr for the resisting force vector and Kf for the stiffness matrix at the free dofs of the structure; information about the structural model is supplied in data structure MODEL, the element properties are supplied in cell array ELEMDATA and loading information is given in data structure LOADING with fields Pref and Uref for a single applied force and a single imposed displacement vector, respectively

## Cross-Reference Information

This function calls:

- Structure performs requested action on group of elements
- Initialize_State initialize state variables of structural model and create STATE
