how to read different columns from excel but write in the same variable in matlab?

Hello everyone, i´m quite new with matlab. I have one excel file and want to read the data with matlab script and plot them.

Due to the data is very big, i can´t fit them only with 4 columns in excel but with 8 columns (as you can see in the image above), i don´t know how i can change my script so that it will read all the 8 columns data but write in the same variable. For example: For A1 A5 A9... and E1 E5 E9... these values are belong to the same variable "Time", so i write in my script:

 num=xlsread('Rxxx.xlsx','Tabelle1','A1:H1048576');
 Time=num(1:4:end,1);

but it doesn´t read the column E1 E5 E9... but i need these value also saved in the same variable "Time"

How can i correct my script so it read read also E to H columns ? I have attached a sample of the excel file.

Thank you and best regards.

I can't understand what exactly you want Mrs.

Do you only need to read column A1 A5 A9... E1 E5 E9....?

%%Read Column A  
A=xlsread('R','A1:A40');
a=A(1:4:end);

%%Read Column E  
E=xlsread('R','E1:E40');
e=E(1:4:end);

Time=[a;e];
