Row indexing: Snow tall records stateSnowRecord contains the amount of snow fall (in cm) for various cities. Rows represent a city and columns represent the snow fall for a given month. Assign citySnowRecord with all elements of row rowNum. Ex: If stateSnowRecord is [17.3; 20.3; 4.8, 6.2] and rowNum is 2, then citySnowRecord is [4.8, 6.2]. Your Solution function citySnowRecord = GetCitySnowFall(stateSnowRecord, rowNum) % GetCitySnowFall: Returns all snow fall values for city in row rowNum % Inputs: stateSnowRecord - matrix of snow fall records for cities for various months % rowNum - specified row of stateSnowRecord to return % % outputs: citySnowRecord - all snow fall values for a given city % Assign citySnowRecord with all elements of a row rowNum. citySnowRecord = 0; end

Variables

Row

A row object has a few fields, which can be accessed with a dot operator or with square brackets: row.index, row["index"], much like in Javascript.

Cells

The cells object, which can also be accessed as row.cells, has fields that correspond to the data column names. For example, cells.Foo returns a cell object representing the cell in the column named Foo of the current row. If the column name has spaces, use the square bracket method, e.g., cells["Postal Code"].

When you need to get the value of the cells variable itself, you need .value at the end, e.g.,

When you need to set or mass edit the values of the columns cells, then you can simply use a GREL expression within quotes, such as just

Alternatively, you can use a Facet which has a built-in edit link next to each value in the Facet panel that allows you to replace large quantities of cell values in one shot.

Cell

A cell object has two fields

Recon

A recon object has a few fields

recon.candidates array can be accessed with something like:

A recon candidate object has a few deeper fields: id, name, type, and score, whose meanings are obvious. type is an array of type IDs. So, the id of the best candidate can be accessed as any one of

You get the idea.

A features object has the following fields:

Record

A record object encapsulates one or more rows that are grouped together. For example, the following data set has 2 records, the first grouping 2 rows and the second grouping 3 rows:

A record object has a few fields, which can be accessed with a dot operator or with square brackets: record.index, record["index"], much like in Javascript.

variable name meaning value the value of the cell in the base column of the current row; can be null row the current row; an object with more fields, with details below cells the cells of the current row, with fields that correspond to the column names; more details below cell the cell in the base column of the current row; an object with more fields, with details below recon the recon object of a cell returned from a reconciliation service or provider; an object with more fields, with details below record one or more rows grouped together to form a record; an object with more fields, with details below
