Here is a simple, Taylor-series-based approach to perturbing a system's states. Suppose your S-function models a dynamic system having a solution invariant, g (X, t), i.e., g is a continuous, differentiable function of the system states, X, and time, t, whose value is constant with time.The obj = imshowpair(A,B) creates a composite RGB image showing A and B overlaid in different color bands. To choose another type of visualization of the two images, use the method argument. If A and B are different sizes, imshowpair pads the smaller dimensions with zeros on the bottom and right edges so that the two images are the same size. By default, imshowpair scales the intensity values of A.

In continuum mechanics, the Cauchy stress tensor, true stress tensor, or simply called the stress tensor is a second order tensor named after Augustin-Louis Cauchy.The tensor consists of nine components that completely define the state of stress at a point inside a material in the deformed state, placement, or configuration. The tensor relates a unit-length direction vector n to the traction.

Invariants The Mooney-Rivlin class of models express the strain energy in terms of invariants, which are in turn expressed as functions of stretch ratios. The invariants are of the product of the deformation gradient with its transpose, \({\bf F}\cdot {\bf F}^T\). This result is symmetric because the product of any matrix with its transpose is.

The invariants of the deviatoric stress are used frequently in failure criteria. Consider a stress tensor \( \sigma_{ij} \) acting on a body. The stressed body tends to change both its volume and its shape. The part of the stress tensor that tends to change the volume of the body is called mean hydrostatic stress tensor or volumetric stress tensor However, many topological invariants (such as the fundamental group and homology) are preserved by homotopy equivalences, which are not homeomorphisms in general, so there is a middle ground.

The principal stresses and the stress invariants are important parameters that are used in failure criteria, plasticity, Mohr's circle etc. For every point inside a body under static equilibrium there are three planes, called the principal planes, where the stress vector is normal to the plane and there is no shear component (see also. The integration with MATLAB can also harness diverse toolboxes available in the MATLAB environment by combining GPenSIM with the Control System Toolbox. The advantages of GPenSIM over other toolboxes are as follows: we can add probability to the gateways, time can be easily added to transitions, and siphons and invariants can also be found.

Partial differential equations (PDEs) have been successful for solving many problems in image processing and computer vision.
