I want to store two variables in an array or list in a loop to collect all my x an y, something like the append function in python, can anyone help me.
Not sure exactly what you're asking... but you could make a list of tuples list:
my_list = [ (0,0), (0,1), (1,1), (1,2) ]
? Is that what you're asking?
I am thinking of:
x_values = () y_values = () for i in range(n); x = i y = i+1 x_values.append(x) y_values.append(y) # Optional x_and_y = zip(x_values,y,values)
I am new to programming so the code might be wronge, but this is what I am trying to do in Matlab.
I don't really understand what you're asking... Can you clarify what you need help with?
I want to append some values to a list in MATLAB.
x_values =  y_values =  for i in range(n); x = i y = i+1 x_values.append(x) y_values.append(y)
How are you wanting to arrange your x and y values? What you have done is correct if you want to create a list of x's and a list of y's whos values are 1 greater than the corresponding x.
Ah I think you want to do it in M-code. I think you could do this:
x = 0:1:n y = 1:1:n+1 % where n would be as far as you would want to go. The syntax is in the form STARTINGNUMBER:INCREMENT:FINALNUMBER
I have two different functions which calculates the speed numerically, what I want to do is plot the difference between them against delta-x usinf Matlab
N = [5,8,10,12] deltax-list =  speed-difference-list =  for n in N: dx = pi./(n-1) deltax-list.append(dx) s1 = function1(n) s2 = function2(n) s = abs(s1-s2) speed-difference-list.append(s)
Is there an append function in Matlab or some other way to send values in to a list or array?
Here is my output on scilab, which is similar to matlab
-->V=[1,2,3,4]; -->V V = 1. 2. 3. 4. -->V(5)=10; -->V V = 1. 2. 3. 4. 10.
I found the idea here http://www.spas.cnrs-gif.fr/ScilabPasapas-Ch17Sc02.html#c
Thanks, it works perfect in Matlab.
