When you use xlsread() with only one output argument, the output is numeric. You need to use xlsread() with at least two output arguments and use the second one as the text string

I have some question - How to extract some rows from a Excel file by string matching?
Example: node_14] t=0.000640 START CCA CW = 2
node_20] t=0.000640 START CCA CW = 2
node_14] t=0.000768 CCA EXPIRES -----------> CHANNEL IDLE
node_20] t=0.000768 CCA EXPIRES -----------> CHANNEL IDLE
node_14] t=0.000960 START CCA CW = 1
node_20] t=0.000960 START CCA CW = 1
node_2] t=0.000960 START CCA CW = 2
node_16] t=0.000960 START CCA CW = 2
From this file I want to extract only the rows which started with node_14. Please suggest some tricks.

[~, txt] = xlsread('G:\Data Sheet\Data sheet.xlsx','Sheet1','K4'); %where (K4) cell is wanted text
Cell_Type = txt{1};
set(handles.text24,'string',Cell_Type);
