Hello, i'm beginner in matlab and i'm asking for help, can someone tell me the signification of this matlab syntax ?
function [output1, output2] = BagOfWords(input, mode, geneIndex, dataForCurrentGene)
switch mode
case 'init'
data = input.data;
nGenesOverall = input.nGenes;
nFeatures = input.nFeatures;
maxNumberOfComponents = input.maxNumberOfComponents;
sparseMatrix = zeros(nGenesOverall,nFeatures);
sparseVector = false(1,nGenesOverall);
% Define the cluster structure
clusterStruct(1,maxNumberOfComponents) = struct(...
'nFeatures', [], ...
'nGenesOverall', [], ...
'beta', [], ...
'sumBeta',[],...
'nGenes', [], ...
'logMarginalLikelihood', [],...
'dataCounts', [], ...
'logicalGeneIDs', [], ...
'N', []);
I didn't understand if input is a simple argument of the function BagOfWords or it refers to requesting user input? Else, what do these instructions (example: nGenesOverall = input.nGenes ) mean ?

Regarding this segment of code
BagOfWords(input, mode, geneIndex, dataForCurrentGene)
Everything inside the parenthesis is an input argument to the function BagOfWords. In the case of this funtion, input is a structure array. The dot notation references data in different fields of that array. For example:
input.nGenes follows the form struct.field
Since you are new to MATLAB, the above example is just a primer. I would encouage you to read through some of the documentation or look into Onramp to learn more about the syntax.
