Matlab cell arrays

These simplifications in the parameter handling are best organised by using structures and cell arrays, as provided by Matlab to supplement the matrix as a basic data type. We introduce both, beginning with structures. 

Many of the fields in the structure s now contain two entries. These are arranged as cell arrays e.g. the field s. Y contains the arrays s. Y 1 and s.Y 2, the field s. t contains the two vectors s.t l and s. t 2, etc. Naturally, more than two data sets can be arranged in this way. A new field, s. nm, contains the number of measurements nm (i.e. data sets). Recall that Matlab requires curly brackets when referring to elements of a cell array. This natural expansion of the structure requires veiy few changes in the other programs. As an example, the central fitting function nglm3. m is not affected at all. 

You can define an array of characters or strings (MATLAB calls it cell array) as follows ... 

NOTE Both String Array and String Array2 are 4 x 1 cell arrays. Always refer to the MATLAB Workspace Browser window to see what kinds of matrices are created as a result of executing any assignment statement (or, command). 

Fig. 6 Multivariate scatter plots of gene expression in selected cell lines (A) and schematic representations of different expression patterns (B-D). The cases were normalized hy array median centering, with the median value of the gene expression in each case centered to zero and the standard deviation to one. The data analysis was performed hy Li Xiao (Eppley Institute for Research in Cancer, UNMC) using MATLAB software (The MathWorks, Inc.)...
