Data Visualisation With MATLAB
3MATLAB is a high performing language for computation, visualization and integration of programming languages in an environment where problems and solutions are expressed in common mathematical notation. MATLAB offers displaying vectors and graphs visualisation in two or three dimensional format including animation.
Plot vectors as lines
Plot a histogram of 1,000 random numbers sorted into 30 equally spaced bins.
x = randn(1000,1);
nbins = 30;
h = histogram(x,nbins);
Plot multiple histograms
