I know the pixel locations where I want to plot the arrows, and I know the magnitude of the vectors I want to plot. Let’s try some variants on the following example. MATLAB can plot a 1 x n vector versus an n x 1 vector, or a 1 x n vector versus a 2 x n matrix (you will generate two lines), as long as n is the same for both vectors. There are samples of the types of problems you have to do in Chapter 5 of your lab manual. 내용 % this mfile plots an arrow with tail at the point (x0, y0) and % tip at the point (x0+a, y0+b). The variable s is a scalar defining a scaling factor to use for the arrows of the field. The vertical component of the plot is then found by using the function that is being plotted and the points along the axis formed by the independent. I could write a program to generate a sine wave of desired frequency through simulate signal. Discover what MATLAB. A problem arises when I try save the figure.
