I can't seem to find out how to plot a piecewise function properly. I can get it by plotting two separate graphs and by using the hold on capability.Since MATLAB® is a programming language, an endless variety of different signals is possible. Here are some statements that generate a unit impulse, a unit step, a unit ramp, and a unit parabola. t = (-1:0.01:1)'; impulse = t==0; unitstep = t>=0; ramp = t.*unitstep; quad = t.^2.*unitstep; All of these sequences are column vectors that inherit ... Plot Single Data Series. Create a stem plot of 50 data values between - 2 π and 2 π. figure Y = linspace (-2*pi,2*pi,50); stem (Y) Data values are plotted as stems extending from the baseline and terminating at the data value. The length of Y automatically determines the position of each stem on the x -axis.Fangjun Jiang on 14 Dec 2011. No. Because you have small coefficients, the range of p is not from 10^2 to 10^20. The maximum value of p is around 7e4. The point is, you can specify any range of T as you want, use linspace () or 100:100:1000, then use array power ".^" not the matrix power "^" to evaluate p, and then you can use plot ().The errorbar function now accepts the same combinations of matrices and vectors as the plot function does. As a result, you can plot multiple data sets at once rather than calling the hold function between plotting commands.The square root function in MATLAB is sqrt(a), where a is a numerical scalar, vector or array. The square root function returns the positive square root b of each element of the argument a, such that b x b = a.Using FPLOT to plot a multi variable function. Learn more about fplot .
