- Categorization functions
  Categorization functions are vector functions that organize data and determine logical groupings. These functions can be used for conditionalizing results and/or bucketing value ranges.
- String functions
  String functions are vector functions that manipulate vectors of strings to provide information about a string or substring, concatenate and split strings, or transform strings based on specified criteria.
- List functions
  List functions are scalar functions that return lists, subsets of lists, and combinations of lists, among other functionality. Lists, along with packages, are compound scalar data types that facilitate programmatic interaction with scalar data values and variables.
- Data-handling functions
  Data-handling functions are vector functions that return a hash value based on an input column or columns.
- Row functions
  Row functions are vector functions that return computational outputs for row inputs, as opposed to column outputs. Row inputs are defined as a space- or comma-separated list of column names.
- SQL compatibility functions
  SQL compatibility functions are functions that treat null values as SQL nulls.
- Financial functions
- System functions
  System functions are special functions in 1010data that return information about users, tables, and other system objects.
- Object functions
  The object functions can be used to check the existence, type, and accessibility of objects such as folders, tables, and queries on the 1010data Insights Platform.
- Miscellaneous functions
  This category of functions contains special functions that don't neatly fit into other categories of functions.

`mattimes(X;Y)`

Returns the element-wise product (Hadamard product) of the two given matrices. (Available as of prod-9)

Function type

Vector only

Syntax

mattimes(X;Y)

Input

Argument	Type	Description
`X`	integer or decimal or matrix model	A scalar value or the name of a column The column specified by this parameter may contain matrix models generated by the 1010data Matrix Functions.
`Y`	integer or decimal or matrix model	A scalar value or the name of a column The column specified by this parameter may contain matrix models generated by the 1010data Matrix Functions.

Note: Either X or Y may be a scalar or scalar column, but not both.

Return Value

Returns a matrix model that is the element-wise product (Hadamard product) of the matrices specified by X and Y.

If X and Y do not have the same dimensions, an error is returned.

Example

Consider the following example:

<table cols="name, data_1, data_2, data_3, data_4" title="mattimes example">
John,8,0,5,1;
John,2,0,1,1;
Mary,3,1,2,2;
Mary,4,1,2,2;
John,5,2,3,1;
John,6,2,3,1;
Mary,7,3,4,2;
Mary,1,3,0,2
</table>
<willbe name="matrix_0" value="g_matrix(name;;;data_1 data_2 data_3 data_4;0)"/>
<willbe name="matrix_1" value="g_matrix(name;;;data_1 data_2 data_3 data_4;1)"/>
<willbe name="mat1_times_mat0" value="mattimes(matrix_1;matrix_0)"/>

For every row, the matrix in mat1_times_mat0 will be the element-wise multiplication of the matrices in matrix_0 from matrix_1.

For example, clicking on the > character in the first row of the matrix_0 column displays the matrix model for those rows where name is John.

Clicking on the > character in the first row of the matrix_1 column displays the transpose of that matrix.

Finally, clicking on the > character in the first row of the mat1_times_mat0 column displays the element-wise matrix multiplication of matrix_0 from matrix_1.
