MATLAB: Retrieve one row from matfile

matfile

i have a matfile with 127*133 values….. i want the 133 values of a particular row…. how to get those values…. please do reply…..

load matfile_name

if the variable with the matrix with 127*133 is X

then

 >> X(1,:)

will return all the 133 values of the 1st row.

x = 1 : length(psdn);
x128 = linspace(x(1), x(end), 128);
p128 = spline(x, psdn, x128);
plot(x128, p128);

You can use evalc to capture the output of type

function tf = getmatv(fname)
  x = evalc(['type(''', fname, ''')']);
  tf = strcmp(x(2:20), 'MATLAB 7.3 MAT-file');
end
