spreadSheetReadM#

Purpose#

Reads and writes Excel files.

Format#

x = spreadSheetReadM(file[, range[, sheet]])#

Parameters:

file (string) – name of .xls, or .xlsx file.
range (string) – range to read or write; e.g., "A1:B20". Default = "A1".
sheet (scalar) – sheet number. Default = 1.

Returns:

x (matrix) – numbers read from Excel.

Examples#

Basic Example#

Read all contents from the file myfile.xlsx located in your current GAUSS working directory.

x = spreadSheetReadM("myfile.xlsx");

Read From a Range#

x = spreadSheetReadM("myfile.xlsx", "B2:D110");

Specify Path and Sheet Number#

x = spreadSheetReadM("C:\\mydata\\myfile.xlsx", "A1", 1);

Portability#

Windows, Linux and macOS

Remarks#

If range is a null string, then by default the read will begin at cell “A1”.

If spreadSheetReadM() fails, it will either terminate and print an error message or return a scalar error code, which can be decoded with scalerr(), depending on the state of the trap flag.

`trap 0`	print error message and terminate program
`trap 1`	return scalar error code

// Will end the program and print an error message
x = spreadSheetReadM("nonexistent_file.xlsx");

// Turn error trapping on
trap 1;
x = spreadSheetReadM("nonexistent_file.xlsx");

// Check to see if 'x' is a scalar error code
if scalmiss(x);
   // Code to handle error case here
endif;

// Turn error trapping off
trap 0;
