In Minitab, you can save matrices with a worksheet and use stored matrices in some analyses. Each stored matrix has a unique ID that starts with an M, for example, M1. You can also assign a name to a matrix. To name or rename a matrix, use the NAME session command. For example, to name matrix M1 "My Matrix", enter the following at the command prompt: NAME M1 "My Matrix".
Stored matrices are not displayed in the worksheet. To view stored matrices in the Session window, choose .
Minitab can also store output in matrices for some statistical analyses, for example, the design matrix for regression, GLM, and DOE procedures.
