height - Number of table rows - MATLAB (original) (raw)
Main Content
Syntax
Description
H = height([T](#btye26y-1-T)) returns the number of rows in the table, T.
height(T) is equivalent to size(T,1).
Examples
Create a table, T.
LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'}; Age = [38;43;38;40;49]; Height = [71;69;64;67;64]; Weight = [176;163;131;133;119]; BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];
T = table(Age,Height,Weight,BloodPressure,'RowNames',LastName)
T=5×4 table Age Height Weight BloodPressure ___ ______ ______ _____________
Smith 38 71 176 124 93
Johnson 43 69 163 109 77
Williams 38 64 131 125 83
Jones 40 67 133 117 75
Brown 49 64 119 122 80 Find the number of rows in table T.
T contains five rows; height does not count the variable names.
Input Arguments
Extended Capabilities
Theheight function fully supports tall arrays. For more information, see Tall Arrays.
This function fully supports code generation. For more information, see Code Generation for Tables (MATLAB Coder).
- Starting in R2021b, the input can be an array, a table, or a timetable. In releases R2019b to R2021a, only tables and timetables are supported.
The height function fully supports GPU arrays. To run the function on a GPU, specify the input data as a gpuArray (Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
Version History
Introduced in R2013b
The height function returns the number of rows of an input array having any data type. In previous releases, callingheight resulted in an error if the input was not a table or timetable.
