ClrErr Catalog > ClrErr Clears the error status and sets system variable errCode to zero. For an example of ClrErr, See Example 2 under the Try command, page 105. The Else clause of the Try...Else...EndTry block should use ClrErr or PassErr. If the error is to be processed or ignored, use ClrErr. If what to do with the error is not known, use PassErr to send it to the next error handler. If there are no more pending Try...Else...EndTry error handlers, the error dialog box will be displayed as normal. Note: See also PassErr, page 73, and Try, page 105. Note for entering the example: In the Calculator application @ on the handheld, you can enter multi-line definitions by pressing · instead of at the end of each line. On the computer keyboard, hold down Alt and press Enter. colAugment( ) colAugment(Matrix1, Matrix2) ⇒ matrix Returns a new matrix that is Matrix2 appended to Matrix1. The matrices must have equal column dimensions, and Matrix2 is appended to Matrix1 as new rows. Does not alter Matrix1 or Matrix2. Catalog > colDim( ) colDim(Matrix) ⇒ expression Returns the number of columns contained in Matrix.
