We can read the text file data in various ways as per our needs and as per application need. WebFrom this article, we learned how and when we use Matlab linear regression. Let see an example for multiple plots in Matlab, we use a subplot function to plot 4 different plots for this we take subplot (2, 2, p)divides the current figure into a 2-by-2 grid, and creates axes in the position specified by p, the value of p decides the how many plots we plot. If options contains a key metadata_collector then the For example, this MathWorks Support Answer uses actxserver to establish a connection between MATLAB and Excel, writes data to a worksheet, and specifies the colors of the cells.
