Keeping data imported from excel

I have managed to import data from excel but as soon as I try to do anything with those variables I have imported they disappear as if they were never imported. I have tried to save them and then use them but that doesn't work. I've tried to import the entire worksheet as one matrix and also each column as its own vector but nothing seems to work. I have also tried using the import wizard, the uiimport function and the xlsxread function and none seems to work. HELP!!! Here is the code I have written thus far: data=uiimport('Copy of Tensile_Data.xlsx'); clear,clc; time=data(:,1); extension=data(:,2); strain1=data(:,3); laod=data(:,4); tensile_stress=data(:,5); tensile_extension=data(:,6); tensile_strain=data(:,7); position=data(:,8); corrected_position=data(:,9);

Never mind I managed to figure out what was wrong. All that fiddling and it turns out my clear,clc: was getting rid of my data because of where it was. X0

This is how I load my excel sheets:

excelsheet         = uigetfile('.xlsx','Select a file');
[num,txt,raw]      = xlsread(excelsheet,'main');

I've never had any issues with "variables" disappearing!
