• Aug 21, 2015 · I just got asked a question about a good way to find the closest value in a vector that was less than a threshold. My solution is fairly short, and demonstrates some of my favorite MATLAB techniques. I will compare also show you an "obvious" solution.
  • The step function is one of most useful functions in MATLAB for control design. Given a system representation, the response to a step input can be immediately plotted, without need to actually solve for the time response analytically. A step input can be described as a change in the input from zero to a finite value at time t = 0
  • I needed a Matlab function for Huffman coding/decoding to be used in a course of mine. Since I was not able to find anything I liked, I wrote it by myself. Here you can find both a "pure .m" version and two C versions: a MEX file one and a stand-alone program to be called via the system call. A warning: since I wrote these functions for my ...

  • The largest value in C maps to the last row in the colormap array. The intermediate values in C map linearly to the intermediate rows of the colormap array. You can adjust this mapping using the caxis function. The CData property of the Surface object stores the values of C.
  • In any n-dimensional space, the two lines L 1 and L 2 are closest at unique points P C = P (s C) and Q C = Q (t C) for which w(s C, t C) is the unique minimum for w(s,t). Further, if L 1 and L 2 are not parallel and do not intersect each other, then the segment P C Q C joining these points is uniquely simultaneously perpendicular to both lines.

  • Its two arguments are the damping ratio and natural frequency [these may be vectors if you want to look at a range of acceptable values]. In our problem, we need an overshoot less than 5% (which means a damping ratio of greater than 0.7) and a rise time of 1 second (which means a natural frequency greater than 1.8).

Just wondering some things about MATLAB, seems like you can do almost anything with it, but would you count it as "programming"? Does the... MATLAB news, code tips and tricks, questions, and discussion! We are here to help, but won't do your homework or help you pirate software.
Thus the order of fit can be changed by changing the value in a single cell, so the suitability of fit can be seen instantly. Find interpolated or extrapolated intersection of two curves defined by two sets of (x, y) points. Find the smoothed curve (constant first derivative) minimum and maximum values of functions defined by a set of (x, y ...

First create a MatLab function and name it fun1.m . function f=fun1(t,y) f=-t*y/sqrt(2-y^2); Now use MatLab functions ode23 and ode45 to solve the initial value problem numerically and then plot the numerical solutions y, respectively. In the MatLab window, type in the following commands line by line. >> [tv1 f1]=ode23('fun1',[0 5],1);
Previously, we've described how to define a line segment in MATLAB, and we will use this definition in our current method for solving for line intersections. A cross product returns the vector perpendicular to two given vectors. Alternatively, if two segments are parallel, the cross product will be 0 (as A X B...
