Row indexing: Snow fall 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].

# Row Indexing: Snowfall Records

This section explains how to index and retrieve snowfall data for various cities using MATLAB functions. Each row in the dataset represents a city, and each column represents the snowfall amount (in cm) for a month. The goal is to obtain snowfall values for specific cities using row indexing.

## Function Explanation

### `GetCitySnowFall`

This function extracts snowfall data for a specified city from a matrix containing snowfall records for multiple cities over several months.

**Inputs:**
- `stateSnowRecord`: A matrix where each row represents a city's snowfall records across different months.
- `rowNum`: The row number specifying which city's snowfall data to retrieve.

**Outputs:**
- `citySnowRecord`: An array containing all snowfall values for the specified city.

#### Code Example

```matlab
function citySnowRecord = GetCitySnowFall(stateSnowRecord, rowNum)
    % GetCitySnowFall: Returns all snow fall values for a city in row rowNum
    % Inputs: stateSnowRecord - matrix of snowfall records for cities for various months
    %         rowNum - specified row of stateSnowRecord to return
    % Outputs: citySnowRecord - all snowfall values for a given city
    
    % Example matrix
    stateSnowRecord = [17.3, 20.3; 4.8, 6.2];
    
    % Assign citySnowRecord with all elements of a row rowNum
    citySnowRecord = stateSnowRecord(rowNum, :);
end
```

## Example of Function Call

The function `GetCitySnowFall` is utilized as follows:

```matlab
GetCitySnowFall([17.3, 20.3; 4.8, 6.2], 2)
```

This call retrieves the snowfall data for the second city, yielding `[4.8, 6.2]`.

## Assessment of Function

Two tests were conducted to verify the function's correctness:

1. **Test Passed**: `GetCitySnowFall([17.3, 20.3; 4.8, 6.2], 2)` successfully returns `[4.8, 6.2]`.
2. **Test Failed**: `GetCitySnowFall([12.6; 8.3; 9.6; 1.5], 3)` expected to return `[9.6]` but failed.
