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)

Can you plot functions 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 .

    Most Matlab plot functions simply plot a pair of vectors as X and Y coordinates. You can assemble those vectors in any fashion you want, including by concatenating vectors representing different functions over different ranges, such as the ranges and functions comprising a piecewise function.
