Create a table from a file with 1468 rows. T = readtable ( "outages.csv", "TextType", "string" ); size (T) ans = 1×2 1468 6. Display the first three rows. If you do not specify an output argument, head does not return a value. It only displays the top of the table. head (T,3) Plot Multiple Histograms. Generate two vectors of random numbers and plot a histogram for each vector in the same figure. x = randn (2000,1); y = 1 + randn (5000,1); h1 = histogram (x); hold on h2 = histogram (y); Since the sample size and bin width of the histograms are different, it is difficult to compare them. G = groupfilter (T,groupvars,method) returns the rows of table or timetable T that satisfy the group-wise filtering condition specified in method. The filtering condition method is a function handle applied to each nongrouping variable. Groups are defined by rows in the variables in groupvars that have the same unique combination of values.

T = readtable ( "outages.csv", "TextType", "string" ); size (T) ans = 1×2 1468 6. Display the last three rows. If you do not specify an output argument, tail does not return a value. It only displays the bottom of the table. tail (T,3)Copy. T (:,1:3)=categorical (T (:,1:3)); % where T is your table variable. That will make selection simple to write--. Theme. Copy. B=T (T.departure== ,:); You can write similar things with cell strings, but in general the syntax is more messy and the categorical variable type has some useful builtin utility functions for summaries and the like ...Description. T2 = movevars (T1,vars) moves the specified variables to the end of the input table. The end is the variable farthest to the right. (since R2023a) For example, to move a table variable named var3 to the end of T1, use T2 = movevars (T1,'var3'). If the last variable of T1 is named var5, then this syntax moves var3 to the right of var5.Rename Table Variables. Variable names are most useful when they are descriptive. So, you might want to rename variables in your table. The recommended way to rename variables is to use the renamevars function. For example, rename the LastName variable of T to PatientName. T = renamevars (T, "LastName", "PatientName") Create Simple Line Plots. Create a table containing three variables. Then pass the table as the first argument to the plot function followed by the names of the variables you want to plot. In this case, plot the Input variable on the x -axis and the Output1 variable on the y -axis. Notice that the axis labels match the variable names. T = table ('Size',sz,'VariableTypes',varTypes) creates a table and preallocates space for the variables that have data types you specify. sz is a two-element numeric array, where sz (1) specifies the number of rows and sz (2) specifies the number of variables. varTypes specifies the data types of the variables. example.sqlquery = ['CREATE TABLE Person(LastName varchar, ' ... 'FirstName varchar,Address varchar,Age int)'];.TT = table2timetable (T) converts the table T to a timetable. The first datetime or duration variable in T becomes the vector of row times of TT. The remaining variables of T become the variables of TT. If T is an M -by- N table without row names, then TT is an M -by- (N-1) timetable. If T is an M -by- N table with row names, then ...
