X—Input data vector|matrix|timetable Input data, specified as a matrix, vector, or timetable of real values. IfXis a vector, it must have at least two samples. IfXis a matrix or timetable, it must have at least two rows. Data Types:double ...
Get ty = datetime(year,3,20); [pk,lk] = findpeaks(avSpots,ty,'MinPeakDistance',years(6)); plot(ty,avSpots,lk,pk,'o') Compute the mean sunspot cycle using datetime functionality. Get dttmCycle = years(mean(diff(lk))) dttmCycle = 10.9600 Create a timetable with the data. Spe...
If A is a table or timetable, then prod(A) returns a one-row table of the products of each variable. (since R2023a) prod computes and returns B as single when the input, A, is single. For all other numeric and logical data types, prod computes and returns B as double. example B...
Get Z = [2+3i 2 -1+4i 3-4i 5+2i -4-2i -2+3i -2 -3i 3i-2i]; polarplot(Z,'*') Plot Coordinates from a Table Copy Code Copy Command A convenient way to plot data from a table is to pass the table to the polarplot function and specify the variables to plot. Create...
