How to plot function using matlab?
显示 更早的评论
how can I solve these problems using 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 .

syms x %requires symbolic toolbox
f = 2 * x - 10 * sqrt ( x ) + 2
figure
fplot(f,[0 5])
f1 = ( 0.5 * x * 4 + 1.1 * x * 3 - 0.9 * x * 2 ) * exp(1) - 0.7 * x
figure
fplot(f1,[-3 10])
%alternatively, you can use fplot, which is part of base MATLAB
f = @(x) x.^2 -10*sqrt(x) +2
fplot(f,[0 5])

you can use fplot by declaring the variable as symbolic like the above shown example

if there is something which is not clear let know else accept the answer so that its understood that the question is solved.
