Create a MATLAB script that generates x-values from -5 to 5 using linspace with 200 value in plot. Define three different y-values as follows:

1. y1=sin(x)
2. y2=cos(x)
3. y3=sin(x)cos(x)

Plot these three curves on the same graph using different line styles and colors. Add appropriate labels for the x-axis and y-axis, a title for the plot, and a legend.
