'width' parameter in kdensity function

Can somebody plase explain me how to use the 'width' paramater of the kdensity function

I suggest you read the "Bandwidth selection" section of this Wikipedia page: http://en.wikipedia.org/wiki/Kernel_density_estimation.

The width parameter is that bandwidth, and can be adjusted accordingly.

You can see the required syntax in "doc ksdensity".

Thanks.

Is there a direct method to find the value(s) of x corresponding to the peak(s) of the kernel density plot?

[the cyclist]

Call

[f,xi] = ksdensity(x);

then

[max_f index_to_max] = max(f);

finds the maxima and

xi(index_to_max)

gives the xi coordinates of the maxima.
