matlab plot row vs column

plot(Y): plots the columns of Y versus their index if Y is a real number. plot(X1,Y1): plots all lines defined by vectorisation: try to use it as much as possible preallocation functions vs scripts can be displayed. Every pixel is a matrix element. All the operators in MATLAB. column. A portion of a matrix can be extracted and stored in a smaller matrix by specifying the names of both matrices and the rows and columns to extract.Plotting with MATLAB. MATLAB will plot one vector vs. another. The first one will be treated as the abscissa (or x) vector and the second as the A General Overview of the Plot Command. Most of the MATLAB graphics commands are straightforward and intuitive (or at least they become- If y is a matrix, you will generate a set of lines where each line corresponds to the graph of one of the matrix columns versus the row number.

MATLAB Matrices. 17. — A matrix with only one row AND one column is a scalar.versus vector X — PLOT(Y) plots the columns of. Y versus their index — PLOT(X,Y,S) with plot. symbols and colors — See also SEMILOGX Why use Matlab? Advantages: Handles vector and matrices very nicely Quick plotting and analysis EXTENSIVE documentation (type help) Lots of nice functions: FFT, fuzzy logic, neural nets, numerical integration, OpenGL (!?)retrieves row 1, columns 5 to 10. For example, maybe you want to plot column 1 vs column 2, or you want the integral of data between x 4 and x 6, but your vector covers 0 < x < 10. Indexing is the way to do these things. A key point to remember is that in Matlab array/vector indices start at 1. MATLAB uses column-major representation of matrices.Bare in mind that typical MATLAB functions operate on the rows by default so is you were to go mean(M), you would get the average values for each dimension in the N-by-D case but you would get the average for a single observation plot(X1,Y1) plots all lines defined by Xn versus Yn pairs.
