# csr(1rheolef)

sparse matrix manipulation (rheolef-7.2)

## NAME

csr - sparse matrix manipulation (rheolef-7.2)

## SYNOPSIS

```
csr [options] file[[.mtx].gz]
```

## DESCRIPTION

Plots or manipulates a sparse matrix. Read from standard input, in the `.mtx` matrix-market format. Write to standard output in either in `matlab` or `postscript` formats.

## EXAMPLES

Enter commands as:

```
  csr -ps     matrix.mtx | gv -
  csr -matlab matrix.mtx > matrix.m
```

## OUTPUT FORMAT OPTIONS

- `-ps`

   Print in the `.ps` postscript format. This is the default.

- `-mtx`

   Print in the `.mtx` format. When the input was not sorted by increasing line and then column order, then, the output is.

- `-matlab`

   Print in the `matlab` sparse format (see e.g. [`octave`(1)](/octave/1.md)).

- `-name` *string*

   Specifies a current name for the sparse `matlab` output option. Default is `a`.

## LIMITATIONS

No render are yet used for the visualization of the sparse matrix: future developments plane to use `gnuplot`.
