I have a file which contains 1000 rows and 6908 column. It looks like this
3.490693e-02 3.604404e-02 3.532657e-02 8.249564e-05 8.572962e-05 8.369483e-05 3.631958e-05 3.830521e-05 3.705194e-05 1.016112e-04 1.060492e-04 1.032492e-04 4.740712e-05 4.949185e-05 4.817630e-05 1.0.....................
How Can i just import this line. At the later stage I need to plot the graphs. When I use importdata workspace, in value column, double/cell. Where should I get more information about this?
Thank you for the help

Which row, specifically?
In general it's much simpler and probably faster to read the full file and do whatever selection is desired in memory.

In these cases, I usually import the data into an Excel spreadsheet (the procedure is 99% automatic), then I import everything in MATLAB from the *.xlsx file: you can choose which rows and columns have to be imported and the type of variable. You can also automatically generate a script or function so that this procedure will be done just the first time.
I hope to have been helpful.
