cell2sos (Signal Processing Toolbox)

Convert a cell array for second-order sections to a second-order section matrix

Syntax

```
m = cell2sos(c)
```

Description

m = cell2sos(c) changes a 1-by-L cell array c consisting of 1-by-2 cell arrays into an L-by-6 second-order section matrix m. Matrix m takes the same form as the matrix generated by tf2sos. You can use m = cell2sos(c) to invert the results of c = sos2cell(m).

c must be a cell array of the form

```
c = { {b1 a1} {b2 a2} ... {bL aL} }
```

where both bi and ai are row vectors of at most length 3, and i = 1, 2, ..., L. The resulting matrix m is given by

```
m = [b1 a1;b2 a2; ... ;bL aL]
```
