Did you try fscanfMat? It could work

	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

		record = mgetl(M);

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