Error using \ Out of memory. Type HELP MEMORY for your options

Question

I need to load two data files each of which have 6 columns and I want to plot the ratio of a column from first data file and another column from the second data file. But I keep getting a memory error. None of the numbers are zeros. I plotted the same in Excel. Worked ok. But I need it in Matlab, What do I do?

My current code is something like this:

    load file1.dat;
    y=file1(:,2);
    time=file1(:,1);
    hold on;

    load file2.dat;
    x=file2(:,5);

    figure;
    plot (t,y/(3*x),'LineWidth',1);
    xlabel('Time (s)');
    ylabel('Mitochondrial Calcium (um)');

This is the error I get:

Error in plotCmyo (line 9) --> File name, line 9 is the one with the plot command
plot(t,y/x, 'LineWidth',1);

Answer 1

Use y./(3*x) to do element-wise division.

Note the operator: ./
