Tq niklas, i know, but how to read array data..
For example my problem is: I want to read. Intensity for every spot in microarray image which is value intensity already store in excel file by using xlswrite...
When i get the value intensity i will compare to one value to get result...this operation i want to execute for all spots in microarray image..:).. Like a loop

I'm not exactly sure what you are asking for, but this code will read data from an excel sheet, and compare each point of the data to a constant value of 5. isLargerThanConstant will have be a matrix with a 1 where the value is larger than the constant and 0 otherwise:
data = xlsread('data.xlsx');
myConstant = 5;
isLargerThanConstant = data>myConstant;
