mtos	Matrix Utility Commands

Convert matrix object to a series or group.

Matrix-TO-Series object: convert the data in a matrix object to a series, alpha, or group.

Syntax

mtos(vector, series[, sample])

mtos(svector, alpha[, sample])

mtos(matrix, group[, sample, prefix])

mtos(matrix, group[, prefix])

The number of observations in the sample must match the row size of the matrix to be converted. If no sample is provided, the matrix is written into the series using the current workfile sample.

For the matrix forms of the command, the prefix parameter is a string. If the target group object does not exist, the group is created and populated with series named <prefix>1, <prefix>2, etc. If the prefix is omitted, the default prefix is “SER”.

Examples

mtos(mom,gr1)

converts the first column of the matrix MOM to the first series in the group GR1, the second column of MOM to the second series in GR1, and so on. The current workfile sample length must match the row length of the matrix MOM. If GR1 is an existing group object, the number of series in GR1 must match the number of columns of MOM. If a group object named GR1 does not exist, EViews creates GR1 with the first series named SER1, the second series named SER2, and so on.

series col1

series col2

group g1 col1 col2

sample s1 1951 1990

mtos(m1,g1,s1)

The first two lines declare series objects, the third line declares a group object, the fourth line declares a sample object, and the fifth line converts the columns of the matrix M1 to series in group G1 using sample S1. This command will generate an error if M1 is not a

matrix.
