• page 256: the variables data and datas are redefined here but the previous values are used in the examples on page 257. To correct the text, replace all references to the variable data with the variable newdata on page 256. Similarly, replace all references to the variable datas on page 256 with the variable newdatas.

  For example

  » data = randn(10,4) % new data for sorting
  data =

  should read

  » newdata = randn(10,4) % new data for sorting
  newdata =

  and

  » [tmp,idx] = sort(data(:,2)); % sort second column
  datas = data(idx,:) % shuffle rows using idx from 2nd column
  datas =

  should read

  » [tmp,idx] = sort(newdata(:,2)); % sort second column
  newdatas = newdata(idx,:) % shuffle rows using idx from 2nd column
  newdatas =

  and

  For example, the last row of data is now the first
  row in datas because the last element in the second column is the smallest element in the second column.

  should read

  For example, the last row of newdata is now the first
  row in newdatas because the last element in the second column is the smallest element in the second column.
