Format#

ord = gdaGetOrders(filename, varname)#
Parameters:
  • filename (string) – name of data file.

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

Remarks#

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:
