General Behaviour

Some general behaviour is shared by many different functions

Arrays of Datasets

If an array of datasets is given then the operation is performed on each dataset in turn, so that

>> wwout = func(ww, params)

where wwout and ww are arrays of datasets and params are the parameters required by the function func, is the equivilent of

for i = 1:length(ww)
    wwout(i) = func(ww(i), params)
end

If all of the parameters are arrays of the same length as the dataset then for some functions this will be equivilent to

for i = 1:length(ww)
    wwout(i) = func(ww(i), params(i)
end

See the matlab online help on individual functions for information on whether they use this syntax.

Property-Value Pairs

Some functions, particularly those in the Graphics package have many optional independent input parameters. Property-value pairs are used to set these.

>> func(input1, input2, ... 'Property', value, 'Property2', value2, ...)

• Properties are always strings that indicate which property will be set
• Values must be in the correct format for the property being set. For instance, if the property is a size, then the value should be a number, but if the property is a label then the value should be a string
• Property-value pairs may be given in any order or omitted
• Property-value pairs are always the final set of arguments to a function

Naming of Functions

talk about _x, _y, _xy convention etc. etc.

Order of Inputs

things like, the dataset always comes first, then any x transformation, then any y transformation.
