I have a vector which represents displacement over time. Its a 7116 by 1 matrix. How do i extract the x and y coordinates from this.

You have only displacement ..values...how do you expect to have (x,y) positions? You can only get the indices....if it is okay..attach the data.

[num,txt,raw] = xlsread('displacement.xls') ;
x = 1:length(num) ;
plot(x,num) ;

mahesh bvm commented: It works! Thank you so much. May I know the difference between the data coded in 'num' and 'raw' outputs. I did go through the xlsread but could not understand it clearly.

num gives you only numeric data.
txt gives you only text data.
raw gives you entire data in a cell array.
Thanks is accepting/ voting the answer.
