In addition to importing numeric tabular data from a text file as a table using readtable, you can also import this data as a matrix into the MATLAB workspace.
MATLAB Online에서 열기 I have a text file that contains complex numbers. My TXT file ("input.txt") has lines formatted as follows: -1+5i 2+9i 10+3i 8+16i How do I import these complex numbers into MATLAB as a matrix of doubles?
I would like to turn the numbers into a matrix. How would I do this? Also, how would I then access a single column in this matrix? Is there a way to have Matlab count the number of rows in the matrix?
