Object Reference : Object View and Procedure Reference : Matrix
Set the row labels in a matrix object.
matrix_name.setrowlabels label1 label2 label3....
Follow the setrowlabels command with a space delimited list of row labels. Note that each row label should not contain spaces unless it is enclosed in quotes. If you provide fewer labels than there are rows, EViews will use the corresponding default row names (“R11”, “R12”, etc...).
mat1.setrowlabels USA UK FRANCE
sets the row label for the first row in matrix MAT1 to USA, the second to UK, and the third to FRANCE.
