MATLAB: Matlab how can I make this inequality

I have an exercise that requires me to plot a function of y=x^2 from 0<=x<pi/2 what would be the right approach for this?

  • There are different ways to display a graph as you are asking, one of the most basic ones being
    1. define the base vector
    step=0.01
    x=[0:step:pi/2]
    2. define the function
    y=x.^2;
    3. display
    plot(x,y)
    grid on
    comments:
    • note the element wise operation implemented with the dot preceding the operator with '.^'
    • plot has many optional fields, check MATLAB help for plot
    • the smaller the step the higher the resolution
    • grid on is also optional
    • the figure window has a marker that can be used for quick checks
    • ; at the end of a command line prevents MATLAB command window showing execution
