Create or append MATLAB matrix with data from Microsoft Excel worksheet
out = MLAppendMatrix(var_name,mdat)
Name of MATLAB matrix to which to append data.
var_name in quotes directly specifies the matrix name. var_name without quotes specifies a worksheet cell address (or range name) that contains the matrix name. Do not use the MATLAB variable ans as var_name.
Location of data to append to var_name.
mdat must be a worksheet cell address or range name. Do not enclose it in quotes.
mdat must contain either numeric data or string data. Data types cannot be combined within the range specified in mdat. Empty mdat cells become MATLAB matrix elements containing zero if the data is numeric, and empty strings if the data is a string.
In this example, B is a 2-by-2 MATLAB matrix. Append the data in worksheet cell range A1:A2 to B:
B is now a 2-by-3 matrix with the data from A1:A2 in the third column.
B is a 2-by-2 MATLAB matrix. Cell C1 contains the label (string) B, and new_data is the name of the cell range A1:B2. Append the data in cell range A1:B2 to B:
B is now a 4-by-2 matrix with the data from A1:B2 in the last two rows.
MLAppendMatrix checks the dimensions of var_name and mdat to determine how to append mdat to var_name. If the dimensions allow appending mdat as either new rows or new columns, it appends mdat to var_name as new rows. If the dimensions do not match, the function returns an error.
If mdat is not initially an Excel® Range data type and you call the function from a worksheet, MLAppendMatrix performs the necessary type coercion.
If mdat is not an Excel Range data type and you call the function from within a Microsoft® Visual Basic® macro, the call fails. The error message ByRef Argument Type Mismatch appears.
