How Chronograph Function

When doing traditional bode diagram control system analysis of ill-conditioned high order SISO systems in V4.2 with Control System Toolbox, I found using these utilities improved the robustness of my results. There's also a nice function to plot an approximate (asymptotic) bode diagram which I...

Writes to file a sorted list of MATLAB functions for all MathWorks products installed on the machine (that the function is executed on). Denotes which functions are built-in to help with syntax highlighting.

Computes the nth moment mean of a function (needs more implentation).m = moment(x, y, n)m = nth moment of yx = domainy = datan = nth moment == 1 by defaultm = int(x^n * y) / int(y)where int is integral over all x integral is calculated using trapezium rule


Platforms: Matlab

The function shows the text string S and prompt the user for an input value guaranteing that the input value is numdoTeric.When the value is not numdoTeric the function gives an error mensage and prompts for a new value until it is numeric.

This function uses rectangle command to plot a circle. The center is to be given in a vector form and radius is a non-negative number.


Platforms: Matlab

Polygamma function of arbitrary order valid in the entire complex plane. This is a generalization of the Psi (or digamma) function. Useful for summing infinite series.

This function uses a non-linear interpolation (Lagrange) to estimate y given x, based on a set of observed x-y points. Coordinates will be sorted based on the x-value of the pair. The x-value provided by the user to calculate y will be estimated using two points left and two points right of the...

Problem definition:This code is to help beginners to understand how reading multiple variables into a function and storing them within a loop without using 'eval' function. This is more of a tutorial code than a specific one.I have multiple variables (X1,X2,X3,...,X10) stored in a mat file, i.e....


Platforms: Matlab

This function can be used to obtain smooth function by increasing number of points of the function.
