- Number of elements found in a matrix row or in a matrix column
- Managing the errors
StatSum (Function) In french: StatSomme Calculates the sum for a series of values.
 Versions 21 and laterVersions 23 and later // Calculate the sum of the elements in row 1 of a matrix
ResSum = StatSum("MyMatrix", 1, False) Syntax
<Result> = StatSum(<Matrix> [, <Row/Column number> [, <Row/Column>]])
<Result>: Real Sum of the values found in the series. <Matrix>: Character string Name of the matrix containing the data, defined by MatCreate. <Row/Column number>: Optional integer Number of the row or column containing the data (1 by default). <Row/Column>: Optional boolean - True (by default) if the series of values corresponds to a matrix column,
- False if the series of values corresponds to a matrix row.
Remarks Number of elements found in a matrix row or in a matrix column The number of elements found in a matrix row or in a matrix column is taken as a reference. This number of elements corresponds to: - the total number of matrix rows, returned by MatNbLine (if the calculation is performed on a column),
- the total number of matrix columns, returned by MatNbColumn (if the calculation is performed on a row).
If the series contain less elements than the matrix, the missing values are automatically filled with 0. These values are taken into account during the calculations. Caution: StatSum returns no error code. To determine if this function has generated errors, use StatError. To get more details on the error, use ErrorInfo with the errMessage constant.
