Trajectory generation for point to point motion with velocity, acceleration, jerk and snap constrain in matlab

The following Matlab project contains the source code and Matlab examples used for trajectory generation for point to point motion with velocity, acceleration, jerk and snap constrain . [Y,T]=GenTraj(A,V,P,Tj,Ts) returns the position, velocity and acceleration profiles for a snap controlled law from the specified constraints on maximum velocity V, maximum acceleration A, desired traveling distance P, Jerk time Tj and Snap time Ts.

Terminal fall velocity of a single spherical particle in a newtonian fluid in matlab

The following Matlab project contains the source code and Matlab examples used for terminal fall velocity of a single spherical particle in a newtonian fluid. Newton number (also called the drag coefficient) and Archimedes number are plotted versus the Reynolds number for the laminar, transition and turbulent flow types using a log-log scale.

Entropy, joint entropy and conditional entropy function for n variables in matlab

The following Matlab project contains the source code and Matlab examples used for entropy, joint entropy and conditional entropy function for n variables. for entropy H = entropy(S) this command will evaluate the entropy of S, S should be row matrix H = entropy([X;Y;Z]) this command will find the joint entropy for the 3 variables H = entropy([X,Y],[Z,W]) this will find H(X,Y/Z,W).

2d mohr's circle in matlab

The following Matlab project contains the source code and Matlab examples used for 2d mohr's circle. Mohr's circle is a graphical technique that permits transformation of stress from one plane to another and can also lead to the determination of the maximum normal and shear stresses.

Quirk multibody dynamics package in matlab

The following Matlab project contains the source code and Matlab examples used for quirk multibody dynamics package. QuIRK is an interactive Matlab command line interface for constructing systems of rigid bodies and joint constraints, solving the equations of motion of those systems when subject to various force expressions, displaying and animating solved systems, and extracting information about the state history and energetics of those systems.

Planck's law in matlab

The following Matlab project contains the source code and Matlab examples used for planck's law. SPECEXITANCE Calculates the spectral radiant exitance for a black body based on Max Planck's law and expressed in (W/m^2·µm) M = specexitance(LAMBDA, T) computes the spectral radiant exitance based on Max Planck's law based on a given temperature (T, in Kelvin) and wavelength (lamda in micro meter [10^-6 m])

The following Matlab project contains the source code and Matlab examples used for compose decompose 3x3 rotation matrix (comp decomp matrix). COMP_DECOMP_MATRIX: compose 3x3 rotation matrix from euler angles (in degrees) or decompose 3x3 rotation matrix to euler angles (in degrees) Input: 1x3 vector of euler rotations around x rotations(1), y rotations(2), and z, rotations(3) or 3x3 rotation matrix Output: 3x3 matrix representing rotations around x, y, and z axis or 1x3 vector of euler angles in degrees

Chen correlation wall temperature calculation in matlab

The following Matlab project contains the source code and Matlab examples used for chen correlation wall temperature calculation. This function uses the 1963 Chen correlation for subcooled boiling flow to calculate the wall temperature of a pipe, based on inlet pressure, an initial guess of the pressure at the pipe wall, and three constants: A, B, C A = h_pb*S, h_pb is the pool boiling coefficient, and S is the Chen suppression factor B = h_c, h_c is the forced convection coefficient

Hydrodynamically interacting spheres at low reynolds numbers in shear flows of a newtonian fluid in matlab

The following Matlab project contains the source code and Matlab examples used for hydrodynamically interacting spheres at low reynolds numbers in shear flows of a newtonian fluid. Stokesian Dynamics, a method developed by Brady and Bossis in the 80s, simulate the 3D motion of hydrodynamically interacting spheres at low Reynolds numbers.
