Gets the orders of a variable in a GAUSS Data Archive.


ord = gdaGetOrders(filename, varname)
  • filename (string) – name of data file.
  • varname (string) – name of variable in the GDA.

ord (Mx1 vector) – orders of the variable in the GDA.


ord = gdaGetOrders("myfile.gda", "x5");


If the specified variable is a matrix or string array, then ord will be a 2x1 vector containing the rows and columns of the variable respectively. If the variable is a string, then ord will be a scalar containing the length of the string. If the variable is an N-dimensional array, then ord will be an Nx1 vector containing the sizes of each dimension.

If gdaGetOrders() fails, it will return a scalar error code. Call scalerr() to get the value of the error code. The error code may be any of the following:

1 Null file name.
2 File open error.
4 File read error.
5 Invalid file type.
8 Variable not found.
10 File contains no variables.
14 File too large to be read on current platform.
