Function matrix_to_csv

src/csv.rs:51–56

Converts a matrix into a comma seperated list of values. As delimiter between the columns the string `sep` is used. As delimiter between the rows a newline is used. # Example ``` # #[macro_use] extern crate rustml; use rustml::*; use rustml::csv::matrix_to_csv; # fn main() { let m = mat![1.0, 2.0; 3.0, 4.0]; assert_eq!(matrix_to_csv(&m, ","), "1,2\n3,4\n") # } ```

(m: &Matrix<T>, sep: &str)

/// # }
/// ```
pub fn matrix_to_csv<T: fmt::Display + Clone>(m: &Matrix<T>, sep: &str) -> String {

    m.row_iter()
        .map(|row| vec_to_csv(row, sep))
        .fold(String::new(), |s, val| s + &val + "\n")
}
