Logarithm values, returned as a scalar, vector, matrix, or multidimensional array. I know i should redirect plhs0 to the vector but i am not getting how exactly should i. If a is an mbyn matrix and you request k singular values, then v is an nbyk matrix with orthonormal columns. Extended capabilities tall arrays calculate with arrays that have more rows than fit in memory. Different machines, releases of matlab, or parameters such as the starting vector and subspace dimension can produce different singular vectors that are still numerically accurate. While figures drawn by the painters renderer are vector plots in the exported pdf, with opengl and zbuffer the pdf contains bitmap pictures of the screen output.
