I nnet to plot two proportional function ??
显示 更早的评论
I plot this function : function gamma=myfun(x) if x<=90 gamma=x ; else gamma=90; end end
now I want to plot another function 'exi' proportional to the first function cad if gamma <= 60 exi = 0 else exi = 1
please someone who can help me
thanks

This works:
myfun = @(x) [x.*(x<=90) + 90*(x>90)];
cad = @(gamma) gamma>60;
x = linspace(0, 100);
gamma = myfun(x);
exi = cad(gamma);
figure(1)
plot(x, gamma, x, exi)
grid
legend('gamma', 'exi', 'Location','NW')

My pleasure!
In that instance, you can simply vectorise the equation you posted:
Vu = exi.*sin(gamma)+2;
^ INSERTED ‘.’ TO VECTORISE THE EQUATION
or to create it as an anonymous function:
Vu = @(exi,gamma) exi.*sin(gamma)+2;
and then evaluated it as another variable, as I did in the code I posted.
Be certain that ‘exi’ and ‘gamma’ are the same size, or the equation assignment or function will throw an error.
