Description:
Space elastic-frames systems has finite element applications are very significant for more civil engineer of areas. Also, in this areas of more books had wrote with general theory, application and methods. I perused more books and all books are not intelligible for space-frame transformation or conversion matrix components.
In this matlab sub-program had perused space-frame system analyis with linear static model. Especially, in sub-functions had compared general and special transformation matrix as axial-rotation matrix (beta-transform).
I wish, this works will be usefully for more researcher by this reason.
