Hello
I am trying to load a large(3gb) .txt file that contains a timeseries. I have tried many ways but nothing seems to work. I cannot understand why
Ws= load('era5_wind_speed_100m_2d.txt', '-ascii'); doesn't work. I get the message: "Unable to read file 'era5_wind_speed_100m_2d.txt'. Input must be a MAT-file or an ASCII file containing numeric data with same number of columns in each row." I know that the file contains numeric data and has the same number of columns in each row. Plus the same code works just fine with similar data. The only way I found opening the file was with: WS = readtable('era5_wind_speed_100m_2d.txt'); but it turns my data into a matrix and I cannot work with it. I cannot even multiply the table with a numer, when i try this, i get: "Operator is not supported for operands of type 'table'". Any ideas how can i Load my data with proper format or how can i turn the operand "table" into a normal matrix
Thanks in advance

If your data is all of the same data type, try readmatrix.
