Matrix Class Function Manual (S-U) |
Purpose
To save as ASCII format by appending its content to an existing file. If the specified does not exist, the function will create a new file, and the result will be exactly the same as using function "saveasc".
if a file name extension is not given, the function assumes an extension of ".txt".
if a path name is not include in the specified file name, the function will search in the current data path, set by command "set path".
Class
Matrix, Matrix_flt, Matrix_int, Matrix_sht, Matrix_uch, Matrix_bln
Usage
{void} object.SAPPASC({String} argm1, [{int} argm2, {int} argm3])
argm1 = an existing file name
argm2 = no of decimal digits (default = value set by command "set precision")

Example:
|

See also (class function)
saveasc
Purpose
To save as binary format by appending its content to an existing file. If the specified does not exist, the function will create a new file, and the result will be exactly the same as using function "savebin".
if a file name extension is not given, the function assumes an extension of ".raw".
if a path name is not include in the specified file name, the function will search in the current data path, set by command "set path".
Class
Matrix, Matrix_flt, Matrix_int, Matrix_sht, Matrix_uch, Matrix_bln
Usage
{void} object.SAPPBIN({String} argm1)

Purpose
To save as Noobeed format. The function creates two files, one for documentation and another for data.
The documentation file will have an extension ".txt". It is actually an ASCII file and must have exactly 6 lines (not including comment lines) , as follows.
|
The data file is in fact a generic binary file. First it stores all element of the first row of the matrix, from the first to the last column, then go to the second row, and does the same thing. Hence the size of the data file will be exactly equal to total number of elements of the matrix multiplied by no of bytes per element (8 bytes in this case).

Usage
For class Matrix
{Matrix} ret = object.SWAPROW({int} argm1, {int} argm2)
For class Matrix_flt
{Matrix_flt} ret = object.SWAPROW({int} argm1, {int} argm2)
For class Matrix_int
{Matrix_int} ret = object.SWAPROW({int} argm1, {int} argm2)
For class Matrix_sht
{Matrix_sht} ret = object.SWAPROW({int} argm1, {int} argm2)
For class Matrix_uch
{Matrix_uch} ret = object.SWAPROW({int} argm1, {int} argm2)

init, Rxyz
Purpose
To update tyhe content of a column of a Matrix. This function is for Matrix_str only.
Class
Matri_str
Usage
{void} object.UPDATE({int} argm1, {int} argm2, {Matrix_str} argm3, {int} argm4, {int} argm5)
argm1 = the column number of the calling Matrix to be updated
argm2 = the column number of the calling Matrix to be used as key data
argm3 = the lookup table matrix
argm4 = the column number of the lookup table matrix containing updating data
argm5 = the column number of the lookup table matrix containing key data
Example:
|
->Table1 = Matrix_str() |
