Convert R objects of class matrix into character strings that represent the matrix in a Matlab style

1	R2Matlab(A, noquote = FALSE)

`A`	a numeric matrix of any dimension
`noquote`	(optional) if `noquote=TRUE` then the returned character vector is printed without quotes.

Matlab reads matrices using a unique one-line notation that can prove useful for storage in databases and importing multiple matrices into a program at once, amongst other applications. This notation is by row, with "[" and "]" to specify the beginning and end of the matrix respectively, ";" to specify a new row and a space between each matrix element. Thus, the R matrix created using matrix(c(0,1,2,0.5,0.1,0,0,0.6,0.6), byrow=TRUE, ncol=3) is equivalent to [0 1 2;0.5 0.1 0;0 0.6 0.6].

R2Matlab takes an R object of class matrix converts it into a Matlab-style character string that may be useful for exporting into databases.

Object of class character representing A in a Matlab style.

  # Create a 3x3 PPM
  ( A <- matrix(c(0,1,2,0.5,0.1,0,0,0.6,0.6), byrow=TRUE, ncol=3) )

  # Code the matrix in a Matlab style
  R2Matlab(A)

  # Print without quotes
  R2Matlab(A, noquote=TRUE)
