readmatrix is truncating and moving decimal

36 views (last 30 days)
I am trying to read in values from an excel file using readmatrix. However when I do, it is truncating the values to 4 decimal places and moving the decimal to the left by 5. I've included some of the values I am reading in and the output values.
expData = readmatrix(filepath, 'Range', [row column]);
Expected:
33972.45132 39866.2488 41830.75072 37335.1956 49199.85501

Are you sure there is not a times 1e5 somewhere before the matrix is displayed. The numbers are likely the same but the format is different. Look at format function, try:
format shortG;
