[Scilab-users] Matrix of characters conversion

[Adrien Vogt-Schilb]

I would read the string matrix, trying to obtain a 1x1 string matrix (or 
at least a 1 column string matri, eg with csvRead)

then use *regexp *to replace several spaces by only one, i guess you 
have to replace " *" by "*" (without the quotes: replace [SPACE][STAR] 
by [SPACE])

then split the matrix where the single spaces are separtors with 
*csvTextScan*
