MLEvalString - Evaluate command in MATLAB

Syntax

Description

MLEvalString(command) passes a command string to the MATLAB software for evaluation. Use this syntax when working directly in a worksheet.

MLEvalString command passes a command string to the MATLAB software for evaluation. Use this syntax in a VBA macro.

out = MLEvalString(command) lets you catch errors when executing MLEvalString in a VBA macro. If MLEvalString fails, then out is a string containing error code or error message. Otherwise, out is 0.

Tips

• The specified action alters only the MATLAB workspace. It has no effect on the Microsoft Excel workspace.

• If MLEvalString fails, then by default you get a standard Spreadsheet Link EX error, such as #COMMAND. To return MATLAB error strings, use MLShowMatlabErrors.

Input Arguments

command

MATLAB command to evaluate. command in quotes directly specifies the command. command without quotes specifies a worksheet cell address (or range name) that contains the command.

Output Arguments

out	0 if the command succeeded. Otherwise, a string containing error code or error message. To return MATLAB error messages instead of error code, use MLShowMatlabErrors.

Examples

Evaluate a MATLAB Command from an Excel Worksheet

Divide the MATLAB variable b by 2, and then plot it:

MLEvalString("b = b/2;plot(b)")

This command only modifies the MATLAB variable b. To update data in the Excel worksheet, use MLGetMatrix.
