changing string variable values

Hi All,

I have a struct with two datasets.

Say

myStruct = 
       myData1 = [124 x 4]
       myData2 = [124 x 4]

Those 4 columns in myData1/2 are myName , myNumber, mySubIndex , summaryData [1 x 60]

All unique names in myName are

restEast restWest restNorth restSouth

I want to change those names, for example all 'restEast' should be changed to 'ownedBySmith'

I can probably do strcmp for restEast and create subset, add another column with 'ownedBySmith' and then delete the column which contained value restEast. I can do that for each name and then vertcat in the end. This is going to be very tedious. Is there a better way to do it in place instead of separating each set by value of 'myName'.

"[124x4]" &nbsp are that cell arrays?
