Plotting a graph for a function with x <- seq(from=-2, to=2, len=10000) on the y axis and x on the x-axis

Hi there,

I'm trying to convert code in R

f<- function(x) {(sin(sin(x^2)) + cos(x/(1+x+2*x^2)) -11/10)}

x <- seq(from=-2, to=2, len=10000)

plot(x,f(x), type='l')

abline(h=0)

to code in Matlab. I've tried a few options like fplot() but it doesn't work for a sequence.

How do I achieve this?

BTW, I'm new to both R & to Matlab

Thanks so much!! Is yline the same as abline? and how do I plot a vertical abline in Matlab? Is there any documentation that I could refer to? Thank you once again!!!

Something like this

f = @(x) (sin(sin(x.^2))+cos(x/(1+x+2*x.^2))-11/10);
x = linspace(-2, 2, 10000);

plot(x, f(x))
yline(0);

Instead of creating your own yline to simulate the X axis, you could change where the X axis is drawn. I don't know if this is more to the original poster's liking.

ax = gca; % or call plot with an output and use ancestor
ax.XAxisLocation = 'origin';

Thanks for the information, Steven.
