6 Data Import and Export
Import from text file grades.txt, using default variables to store the data:
uiimport grades.txt
whos
Name Size Bytes Class Attributes
data 4x3 96 double
rowheaders 4x1 272 cell
textdata 4x1 272 cell
Example 2—Partial Text File with Row Vectors. Import from the same
file as in the above example, but this time select Create vectors from each
row using row names. Also, clear the checkbox next to variable John so that
this one vector does not get written to the workspace:
whos
Name Size Bytes Class Attributes
Ann 1x3 24 double
Martin 1x3 24 double
Rob 1x3 24 double
Example 3—Binary Data Assigned to a Structure. Save numeric and
text data in binary format in file importtest.mat and use the Import Wizard
toimportthebinaryfileintotheworkspace.
C = [1 2 3 4 5;6 7 8 9 10];
D = 'a test string';
save importtest C D
clear
s = uiimport('importtest.mat')
s =
C: [2x5 double]
D: 'a test string'
