MATLAB: How to fill each row of a matrix with vectors created separately

MATLABmatrix manipulationvector

I created 4 vectors and I want to insert them into a matrix to print them all together. Is there a function that would allow me to do this? My vectors are:

A=[matriz1,matriz2,matriz3,matriz4];
B=[matriz5,matriz6,matriz7,matriz8];
C=[matriz9,matriz10,matriz11,matriz12];
D=[matriz13,matriz14,matriz15,matriz16];

You may use the following notation:

A(1,:)=vec1
.
.
A(4,:)=vec4

A(1:size(A,1),:)=[vec1;vec2;vec3;vec4];

Looks like your while loop counter index, k, is going above the row count of matriz. For instance, check these simpler codes out to replicate your error and to fix it.


matriz = ones(1000, 3);
ano_ini = 1;
k = 1;
j = -1;
while matriz(k,3)==ano_ini %Error: Index exceeds matrix dimensions
    matriz(k,1)=j;
    k=k+1;
end
matriz = ones(1000, 3);
ano_ini = 1;
k = 1;
j = -1;
while matriz(k,3)==ano_ini
    matriz(k,1)=j;
    k=k+1;
    if k > size(matriz, 1); break; end  %break while loop before an error occurs
end

MATLAB: How to permute the rows and columns in a matrix

Swapping the columns

 idx = [4 2 3 1];
 B = A(:,idx);

Swapping the rows

 idx = [3 2 1 4];
 C = A(idx,:);
