Create or overwrite MATLAB matrix with data from Microsoft Excel VBA variable

Syntax

MLPutVar ML_var_name, VBA_var_name
out = MLPutVar ML_var_name, VBA_var_name

Description

MLPutVar ML_var_name, VBA_var_name creates or overwrites matrix ML_var_name in MATLAB® workspace with data in VBA_var_name. Creates ML_var_name if it does not exist. If ML_var_name exists, this function replaces the contents with data from VBA_var_name.

out = MLPutVar ML_var_name, VBA_var_name lets you catch errors when executing MLPutVar. If MLPutVar fails, then out is a string containing error code. Otherwise, out is 0.

Input Arguments

ML_var_name

Tips

  • Use MLPutVar only in a macro subroutine, not in a macro function or in a subroutine called by a function.

  • Empty numeric data cells within VBA_var_name become numeric zeros within the MATLAB matrix identified by ML_var_name.

  • If any element of VBA_var_name contains string data, VBA_var_name is exported as a MATLAB cell array. Empty string elements within VBA_var_name become NaNs within the MATLAB cell array.
