Read tab-delimited file
tdfread
opens the Select File to Open dialog box for interactive
selection of a data file, and reads the data from the file you select.
tdfread
can read data from tab-delimited text files with
.txt
, .dat
, or .csv
file
extensions.
Select a file that has variable names in the first row and values separated by tabs in
the remaining rows. tdfread
creates a variable in the workspace for
each column of the file, and names each variable according to its first row value.
If a column contains only numeric data in all rows except the first, then
tdfread
creates a double
variable.
Otherwise, tdfread
creates a char
variable.
After importing all values, tdfread
displays information about
the imported variables, such as their size, bytes, and class.
tdfread(
creates variables from the
data in filename
)filename
, which is either the name of a file in the current
folder or the complete path name of a file.
returns a
structure s
= tdfread(___)s
in which each field contains a variable. Specify any of
the input argument combinations in the previous syntaxes.
Consider using the readtable
, readmatrix
, or
readcell
MATLAB functions to import data. These functions provide more flexible data importing
options than tdfread
.
