WebbThere are the various operations of lines in Matlab in which line width is one of the operations. Line width is used to adjust (increase) the width of any object. Line width operation mostly executes inside the plot operation. Plot operation is used to plot the … Webbwhich has very wide capability. Basically, it writtenis as plot(x, y), where is ytaken to be a function of x. Figure 1 shows a simple example given by: >> x = 0:0.1:8; >> y = 8*exp(-1.1*x); >> figure >> plot(x, y) Figure 1 . Alternatively, if and x y are defined as independent vectors, they must have the same length: >> x = 0:1:8;
