Question

The following code must be written in matlab

How to convert a 4d unit8 matrix of size

28 28 1 50000

in Matlab to a matrix of size 784*5000

Give an example that clearly solves this issue. Thanks

Answer 1

The problem here is either the first matrix has to be 28*28*1*5000 or the second matrix has to be 784*5000*10 because without these changes the sizes of the matrices are different.

So, I used two matrices to demonstrate the 2 cases.

a1 is of shape 28*28*1*5000

b1 is of shape 784*5000

a2 is of shape 28*28*1*50000

b2 is of shape 784*5000*10

CODE :

clear all; close all; clc;

a1 = ones(28,28,1,5000,'uint8');
b1 = reshape(a1,784,5000);

a2 = ones(28,28,1,50000,'uint8');
b2 = reshape(a2,784,5000,10);
