In JusteRaimbault/r-spatialmorphology: What the package does (short line)

Usage

distanceSubMatrix(n_rows, n_cols, raster_cols, row_offset, col_offset)

Arguments

n_rows
n_cols
raster_cols
row_offset
col_offset

Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (n_rows, n_cols, raster_cols, row_offset, col_offset) 
{
    di = matrix(rep(cumsum(rep(1, n_rows)), n_cols), nrow = n_rows) + 
        row_offset
    dj = matrix(rep(cumsum(rep(1, n_cols)), n_rows), nrow = n_rows, 
        byrow = TRUE) + col_offset
    return(sqrt((abs(di - dj)%/%raster_cols)^2 + (abs(di - dj)%%raster_cols)^2))
  }
