MathWorks is the leading developer of mathematical computing software for engineers and scientists. It involves creating a long vector from the 'Probe4' array, matching it with an appropriate vector for 'Y', and then doing a simple linear regression. So we mustnt set the axis limits because some data sets might be long, and if we set the short axis limits, the whole data set will not be covered on the plot. The steps for multiple plotting of the data using subplot statement:- Step 1: We take variables and assign a value and plot 1 st signal. The rest of the code is straightforward. By default, new plots clear existing plots and reset axes properties, such as the title. your location, we recommend that you select: . Yes, the second header line can be deleted but may be better to inverse with first line; to retain for reference. i have attached an image as an example., It would be helpful if you could also upload your data, preferably as a. it an not have to write specific code to import it. It can't swap them, but you can pass a variable to readtable() to tell it to skip that one header line. Total number of columns can be unknown; but with this dataset, it can be counted.
