MATLAB: How to define range using a variable in xlsread

Question

I would like to read a row from excel file in Matlab. The row's staring and end columns are defined but I would like to use a variable to define the row number. I have tried the following:

row_no = 50;
x = xlsread('yourfile.xlsx', 'sheet', ['B50:EHI' num2str(row_no)]);

The above code allows the use of variable `row_no` to define the end cell `EHI50`. But can this also be done for referring to the starting cell `B50`?

Answer 1

doc sprintf

can create a string out of variables, e.g.

columnStr = 'B';
startRow = 50;
endRow = 50;
sprintf( '%s%i:EHI%i', columnStr, startRow, endRow )

Or if you always want the same start and end row you can simplify it by using the same variable for both.
