To plot two lines with different line widths, you can use either of these approaches. 1. Return the two “Line” objects as an output argument from the “plot” function and then set the “LineWidth” property for each. 2. Use the “hold on” command to plot the two lines separately. streamline (X,Y,U,V,startX,startY) returns plotted streamlines for 2-D vector data. The inputs X and Y are vector data coordinates, U and V are vector data, and startX and startY are the starting positions of the streamlines. streamline (U,V,startX,startY) uses the default coordinate data for U and V. The ( x, y) location for each element in U ...red is the facecolor (PolyGon Color) of patch we passed in the 3rd argument of the function. and black is by defailt EdgeColor of patch object.

Create a newline character. Then use + to concatenate the newline character and more text onto the end of a string. str = "In Xanadu did Kubla Khan" ; str = str + newline + "A stately pleasure-dome decree". str = "In Xanadu did Kubla Khan A stately pleasure-dome decree". Although str displays on two lines, str is a 1-by-1 string.
