Out of memory ?

when two text file of 10 mb each is processed for finding out the cross co-realtion Between Them Matlab Gives Following error

??? Error using ==> fft Out of memory. Type HELP MEMORY for your options.

Error in ==> C:\MATLAB6p5\toolbox\signal\signal\xcorr.m (vectorXcorr) On line 149 ==> X = fft(x,2^nextpow2(2*M-1));

Error in ==> C:\MATLAB6p5\toolbox\signal\signal\xcorr.m On line 54 ==> [c,M,N] = vectorXcorr(x,autoFlag,maxlag,varargin{:});

How Will i increase the memory of Matlab ,Im using Win xp sp2

Answer 1

[Andreas Goser]

You may want to decrease the consumed memory...

But for increasing the memory see this link. In particular, look at the 3 GB switch.

Will u please elaborate ?

[Andreas Goser]

Well on which part? Saving memory or increasing memory?

I am using 64 bit operating system and 64 bit matlab. Still i am getting this error Error using svd Out of memory. Type HELP MEMORY for your options. how to fix it.. pls help me

[Steven Lord]

Please show your call to the svd function (all the inputs and outputs) and state the sizes of any variables that you're passing into svd as inputs.

[Annie micheal]

function [U, S] = pca(X) % PCA for large matrices. % Runs principal component analysis on the dataset X % [U, S] = pca(X) computes eigenvectors of the covariance matrix of X % Returns the eigenvectors U, the eigenvalues (on diagonal) in S % Useful values [m, n] = size(X);

U = zeros(n); S = zeros(n);

eps = (X' * X) ./ m; [U,S,~] = svd(eps); end

size of X is 11525*6400, the data type of X is double
