How do you plot equations in octave?

octave#:#> plot(x,y,’b–‘,’linewidth’,3) will plot x and y as a thick, blue, dashed line. The next example consists in plotting two different functions on the same axis. Specifically, we will plot the functions f1(x) = sin(x) and f2(x) = sin(x2) from x = 0 to x = 2π, using equally spaced points on the x-axis.

How do you plot a function on a graph in Matlab?

1. Use the plot command to plot the function f ( x ) = x 2 − 10 √ x + 2 for 0 ≤ x ≤ 5 . 2. Use the plot command to plot the function f ( x ) = ( 0.5 x 4 + 1.1 x 3 − 0.9 x 2 ) e − 0.7 x for − 3 ≤ x ≤ 10 .

How do you plot a graph in octave?

Plot using Octave When plotting in Octave you plot points having their x -values stored in one vector and the y -values in another vector. The two vectors must be the same size. Octave inserts lines between the points. If you want a smoother graph, make a longer x -vector.

How do you plot an XY graph in MATLAB?

MATLAB – Plotting

  1. Define x, by specifying the range of values for the variable x, for which the function is to be plotted.
  2. Define the function, y = f(x)
  3. Call the plot command, as plot(x, y)

How do you write an exp function in MATLAB?

Description. e z = e x ( cos y + i sin y ) . Use expm to compute a matrix exponential.

How do you plot multiple lines on one graph in Python?

Python Code Editor:

  1. import matplotlib. pyplot as plt.
  2. x1 = [10,20,30]
  3. y1 = [20,40,10]
  4. plt. plot(x1, y1, label = “line 1”)
  5. x2 = [10,20,30]
  6. y2 = [40,10,30]
  7. plt. plot(x2, y2, label = “line 2”)
  8. plt. xlabel(‘x – axis’)

What is the basic plot command for FreeMat?

This is the basic plot command for FreeMat. The general syntax for its use is plot( ,{linespec 1}, ,{linespec 2}…,properties…) where the arguments can have various forms, and the linespecarguments are optional.

Is Octave compatible with MATLAB?

The syntax of Octave is identical to that of Matlab in our tests. However, we found during our tests that FreeMat lacks a number of functions, such as kron for Kronecker products, pcg for the conjugate gradient method, and mesh for three-dimensional plotting. Otherwise, FreeMat is very much compatible with Matlab.

What is the difference between octave and Scilab?

Once again, Octave and FreeMat use the exact commands for plotting and similar for annotating as Matlab whereas Scilab requires a few changes. For instance in Scilab, the pi command is defined using %pi and the command grid on from Matlab is replaced with xgrid or use the translator to create conversion.
