A function is used to draw the plot of the condition number of signature matrices of all sizes, from a handful of genes in one extreme to the whole signature in the other.

an array with the number of genes used to calculate the condition numbers of signature matrices, default stepwise = 20 |

`cond` |

## toy data example:
step <- seq(20,1000, by=20) #every 20 genes
## cell type-specific gene expression matrix:
x.signature <- matrix(rexp(2000),ncol=2)
sig.cond <- sapply(step, function(x) kappa(scale(x.signature[1:x,])))
function (step, cond)
