My data is 1×51 size in csv, when I use readmatrix function to specify "Range" to import 1 to 50 data, it is empty, or import other range data, the result is all data, my sample code is as follows, thanks in advance! (The "T2.csv" is in the attachment)
T2 = readmatrix("T2.csv","Range","B1:AY1") % empty ???
T2 =
[]
T2 = readmatrix("T2.csv","Range","A1:E1") % all data is imported ???
T2 =
Columns 1 through 12
0 1.0000 0.7382 0.5086 0.3818 0.3015 0.2462 0.2058 0.1750 0.1509 0.1316 0.1157
Columns 13 through 24

Columns 37 through 48
0.0106 0.0095 0.0085 0.0076 0.0067 0.0058 0.0050 0.0043 0.0036 0.0029 0.0023 0.0016
Columns 49 through 51
0.0011 0.0005 0
T2 = readmatrix("T2.csv","Range","B1:E1") % also empty ???
T2 =
[]
The results of the above experiment are very strange, but the import of data from "range" using the "xlsread" function is normal

Why to specufy posititon? Read whole matrix and pick the required one using indexing.
