- Matrix existence
- Matrix size
MatWrite (Function) In french: MatEcrit Writes an element into a matrix.
// Assign 6 to the element (row 2, column 2)
ResWrite = MatWrite("MyMatrix", 6, 2, 2) Syntax
<Result> = MatWrite(<Matrix> , <Value> , <Element row> , <Element column>)
<Result>: Boolean - True if the writing was performed,
- False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.
<Matrix>: Character string Name of the matrix to be used, defined with MatCreate. <Value>: Real Value given to the specified element. <Element row>: Integer Row of the element to initialize. <Element column>: Integer Column of the element to initialize. Remarks A matrix must exist before it can be filled. To check the matrix existence, use MatExist. The matrix size is managed dynamically. If the coordinates (row and columns) of the element to insert into the matrix are greater than the matrix dimension (total width and total height of the matrix), the element is added at the specified position. In this case, the matrix is filled with zeros. For example: MatWrite("MyArchive", 9, 2, 4)
