Hi, I'm trying to interpolate a two-D table. It should be straight forward, but it won't run:
%[filename pathname]=uigetfile('*.prn','Select a Data File"'); % inputfile=strcat([pathname filename]); % [sig] = textread(inputfile,'%f ');
for i=1:25937;
sig(i)=i;
end;
sizeRow = floor(size(sig)/701);
clear tS;
for j=1:37
[tS(1,j)] = sig(j);
end
for i = 2:701
for j=1:37
[tS(i,j)] = sig(j+(i-1)*sizeRow(1));
end;
end;
% Interpolate
tSSize=size(tS);
RowSize = 1:tSSize(1);
ColumnSize = 0:2.5:90;
InterpTS = interp2(ColumnSize,RowSize,...
tSSize,4.5,66)

first loop can be done by sig=1:25937
second loop can be done by ts=sig(1:37)

You probably mean this at your last line.
InterpTS = interp2(ColumnSize,RowSize,...
tS,4.5,66)

What are 4.5 and 66 values?
