MATLAB: How to pass in multiple arguments to a function using a cell array in MATLAB 7.5 (R2007b)

I want to call a function which needs multiple input arguments. I wish to call this function using a single cell array to pass in these multiple arguments.

It is possible to pass in multiple input variables to a function using a single cell array. The following example illustrates how this can be achieved.

Given the following function:

function myfun(arg1, arg2)
disp(arg1);
disp(arg2);

It can be called in the following way:

% Merged function call using a cell array.
mergedVariable = {1 'test'};
myfun(mergedVariable{:})

FASTINSERT processes each record separately, that is why you will receive an error message when passing:

exdata =

[cell 1x4] [cell 1x4] [cell 1x4] [double 1x4]

However it is possible to pass multiple records in one call to FASTINSERT if your data is converted to the following format:

exdata =

[cell 1x1] [cell 1x1] [cell 1x1] [double 1x1]

The reshaping of the cell can be done by a simple FOR loop or the CELLFUN command:

exdata = cell(dima,4);
for i = 1:dima
     exdata{i,1} = mydata1(i);
     exdata{i,2} = dates(i);
     exdata{i,3} = ID(i);
     exdata{i,4} = mydata2(i);
end

MATLAB: [] appears after a function

According to the function documentation, those square brackets contain any output arguments. Because the square brackets you show in your question contain zero variables, that function has zero output arguments.

function [A,B,C,D] = myfun(...) % 4 output arguments
function [A,B,C] = myfun(...)   % 3 output arguments
function [A,B] = myfun(...)     % 2 output arguments
function [A] = myfun(...)       % 1 output arguments
function [] = myfun(...)        % 0 output arguments

For one or zero output arguments the square brackets can be omiited entirely:

function A = myfun(...)        % 1 output arguments
function myfun(...)            % 0 output arguments
