The proposed system involves converting the input image into a format such that the number of objects can be calculated based on the connected components present in the enhanced image. This project work also aims at determining the correct value of density by clearing the objects touching the borders of the image.
Its text-based programming language MathScript uses .m-file-script syntax providing some compatibility with MATLAB and its clones. LAPACK provides Fortran 90 routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems and the associated ...
For example, the second-order equation y′′ = −y can be rewritten as two first-order equations: y′ = z and z′ = −y. In this section, we describe numerical methods for IVPs, and remark that boundary value problems (BVPs) require a different set of tools. In a BVP, one defines values, or components of the solution y at more than one ...

In practical terms, the distinction between DAEs and ODEs is often that the solution of a DAE system depends on the derivatives of the input signal and not just the signal itself as in the case of ODEs; [3] this issue is commonly encountered in nonlinear systems with hysteresis, [4] such as the Schmitt trigger. [5]
For an arbitrary system of ODEs, a set of solutions (), …, are said to be linearly-independent if: + … + = is satisfied only for = … = =.A second-order differential equation ¨ = (,, ˙) may be converted into a system of first order linear differential equations by defining = ˙, which gives us the first-order system:
