You can use evstr for that
example
M=["1     2   5.54"
        "3.45 8 -123"
        "0           -432.512  -0.435"]

-->evstr(M)
 ans  =
 
    1.      2.         5.54   
    3.45    8.       - 123.   
    0.    - 432.512  - 0.435

	Dear All

	 

	How can I convert a matrix of characters into integers when the separator has different number of spaces ?

	 

	The spaces come probably  from a printf format such as :     printf("%10d\n",var)

	 

	I 'm currently using csvTextScan and I've some troubles/errors  with csvRead ...

	 

	Example :

	! 300006     12799     24678     17504     21558    212801     24680     17508     21560 !

	 

	NB:

	-          I read first an ascii file

	-          I removed some specific lines directly in the matrix

	-          Then I'm trying to convert the matrix of characters into a matrix of intergers

	 

	Thanks for any suggestion

	 

	Paul

	Nodes_char(1:nbre_elem) = record(1:3:nl);
	 
	// convert
	Nodes = csvTextScan(Nodes_char,"     "); // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
