How to loop strings

How would

zzsprintf(fmt,vecs.'); % will give me a string that look like the following
      "<-0.65,-0.9,-0.2>",  @"<-0.23,-0.48,-0.28>",  @"<-0.21,-0.5,-0.28>",  @"<-0.16,-0.6,-0.3>",  @"<-0.19,-0.63,-0.32>",  @"<-0.69,-0.74,-0.12>",  @"<-0.66,-0.63,-0.30>",  @"<0.34,0.11,-0.54>",  @"<0.18,-0.60,-0.53>",  @"<0.23,0.2,-0.58>",  @"<0.42,-0.44,-0.62>",  @"<0.43,-0.49,-0.65>",  @"<0.25,-0.55,-0.68>",  @"<0.45,-0.64,-0.84>",  @"<-0.13,-0.56,-0.47>",  @"<0.92,-0.80,-0.76>",  @"<0.17,-0.62,-0.48>",  @"<0.56,-0.98,-0.47>",  @"<0.16,-0.85,-0.52>",  @"<0.17,-0.85,-0.44>",  @"<0.45,-0.89,-0.65>",  @"<0.10,-0.56,-0.69>",  @"<-0.65,0.68,-0.85>",  @"<0.21,-0.63,-0.53>",  @"<-0.11,0.76,-0.53>",  @"<0.31,-0.46,-0.98>",  @"<0.32,-0.51,-0.93>",  @"<0.36,-0.58,-0.82>",  @"<0.33,-0.66,-0.65>",  @"<0.43,-0.56,-0.65>",  @

The output I'm hoping to get is set line in front 3 lines of string and set line as displayed below. The case number will change as each irrigation. below is sample of 4 first loop 1st

( "Case1", "Case1", "Node", "Vector", 15, [ @
"Node 270252", "Node 270296" ["<-0.65,-0.9,-0.2>",  @
"<-0.23,-0.48,-0.28>",  @
"<-0.21,-0.5,-0.28>",  @
"<-0.16,-0.6,-0.3>",  @])
"Case1", "Displacement", "Nodal", "",  @
"Static", ["Node 270252"], "FEM"

2nd

 ( "Case2", "Case2", "Node", "Vector", 15, [ @
"Node 270252", "Node 270296" ["<-0.16,-0.6,-0.3>",  @
"<-0.19,-0.63,-0.32>",  @
"<-0.69,-0.74,-0.12>",  @])
"Case2", "Displacement", "Nodal", "",  @
"Static", ["Node 270252"], "FEM"

3rd

( "Case3", "Case3", "Node", "Vector", 15, [ @
"Node 270252", "Node 270296" ["<-0.66,-0.63,-0.30>",  @
"<0.34,0.11,-0.54>",  @
"<0.18,-0.60,-0.53>",  @])
"Case3", "Displacement", "Nodal", "",  @
"Static", ["Node 270252"], "FEM"

4th

( "Case4", "Case4", "Node", "Vector", 15, [ @
"Node 270252", "Node 270296" ["<0.23,0.2,-0.58>",  @
"<0.42,-0.44,-0.62>",  @
"<0.43,-0.49,-0.65>",  @])
"Case4", "Displacement", "Nodal", "",  @
"Static", ["Node 270252"], "FEM"
