Hi all.
I have a matrix M:
First column is X ans the rest are Ys. Lets say 100 of them (1000 sometimes).
So far I can plot it like
plot(M(:,1), M(:,2),M(:,1),M(:,3)… and so on and so on)
Is there any possibility to do it in matlab way? Like:
plot(M(:,1),M(:,2:end))
This is main thing stopping me from migration from matlab to Python now

Hi Piter,
Does the following do what you want?
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(10)
y = np.random.random((10, 5))
M = np.column_stack((x, y))
plt.plot(M[:, 0], M[:, 1:])
plt.show()
Python indices start from zero, Matlab indices start from 1.

Is there any possibility to do it in matlab way? Like:
You can’t index arrays with regular parentheses in Python. How do you distinguish function calls from array-matrix indexing in Matlab?

Thanks.
