Step function - unit step with Matlab.
Saving a complex double array causes the imaginary part of the data to be lost, as MATLAB cannot load nonnumeric data ('i'). In order to be able to read the file with the MATLAB load function, all of the variables must have the same number of columns. If you are using a program other than MATLAB to read the saved data this restriction can be.
MATLAB (and most mathematical software) knows the exponential function as exp(x) so the number e in MATLAB is exp(1). The natural logarithm ln MATLAB (and most mathematical software) knows the natural logarithm as log(x).
Sometimes a script is a useful starting point in developing a MATLAB function. When I'm starting to write a new function, but I'm uncertain about the command syntax or the actual sequence of commands I want to use, I'll use the diary command to record my tests. After I get the correct command sequence I close the diary file and open it with a.
Write a Matlab function that takes in a vector of positions x, the time interval between each sampled point h, and outputs the acceleration vector a. You will need to look up the one-sided difference formulas for the second derivative. One reference is provided here. Note that this function can be interpreted more generally: input x, output.
Write your user-defined function, e.g., mycross(v1, v2), and can not use MATLAB built-in function cross.
MatLab has an API where you can call MatLab functions via Python. The idea, however, was not to use MatLab, but the same algorithm works the same way using only Python and NumPy, and the GNU.
Give it a name such as test1.m Now type test1 in the Matlab window and it will ask for a number, square it and then display the result.
