# how to convert H(b < g) = 2*100 – H(b < g) from MATLAB to python

i have the code like below H = [10 20 30 40 50 60] b = [5 9 28 59 22 18] g = [9 9 10 25 30 5] H(b < g) = 2*100 – H(b < g) the result is like this : H(b < g) = 2*100 – H(b < g) i… Read More how to convert H(b < g) = 2*100 – H(b < g) from MATLAB to python

I want to add blocks to MATLAB simulink model by command line. I used add_block command to add a Constant block to my model by following command and it worked add_block(‘simulink/Sources/Constant’,’MyModel/ConstValue’) But when I try to add’Chart’ to my model by the following command, add_block(‘stateflow/Chart’,’MyModel/Chart’) It causes an error: Error due to multiple causes. Caused… Read More add-block command in MATLAB

# MATLAB set class `size`

classdef Dog end d=Dog(); can size(d) be controlled? Is there some property to set or method to overload? Ultimately I have like d.data = [1, 2, 3] and want length(d) == 3. I’m aware I can make d.length(). As an aside, is there a list of MATLAB "magic methods", i.e. functions that control interaction with… Read More MATLAB set class `size`

# Creating a structure within a structure with a dynamic name

I have large data sets which i want to work with in matlab. I have a struct called Trail containing serveral structures called trail1, trail2 … which then contain several matrices. I now want to add another point to for instance trail1 I can do that with Trail.trail1.a2rotated(i,:) = rotpoint’; the problem is that i… Read More Creating a structure within a structure with a dynamic name

# I need Assistance with my Function Problem, I am getting zero for all my answers

This is the problem I am trying to solve: Write a function my_is_orthogonal(v1,v2, tol), where v1 and v2 are column vectors of the same size and tol is a scalar value strictly larger than 0. The output should be 1 if the angle between v1 and v2 is within tol of π/2; that is, |π/2−θ… Read More I need Assistance with my Function Problem, I am getting zero for all my answers

# What is the pythonic way of "iterating" over a single item?

I come across this issue often, and I would be surprised if there wasn’t some very simple and pythonic one-liner solution to it. Suppose I have a method or a function that takes a list or some other iterable object as an argument. I want for an operation to be performed once for each item… Read More What is the pythonic way of "iterating" over a single item?
