Scatter plot of two matrix of same size

I have two matrix of same size (293 X 293 matrix) and i want to plot the scatter plot of these data as one matrix on X axis and one matrix on Y axix. but the matlab showing the error.

>> y=readmatrix('chr8norm_Nmin_matrix.txt');

>> x=readmatrix('chr8_spatial_distance_0.5_matrix_test.txt');

>> scatter(x,y)

Error using scatter (line 78)

X and Y must be vectors of the same length.

please help me out to solve this problem
