MATLAB: Replace numbers by strings

replace string

Hi,

I have a matrix A= 1×100, and now I want to replace if numbers in A < 90 by 'case1' and A>=90 by 'case 2'

Could anyone offer some help?

Thanks

Best Answer

One way:

A = randi([80,100], 1,100 ); % Sample data
C = cell(size(A));
C(A<90)={'case1'};
C(A>=90)={'case2'};

result

>> C(1:5)
ans = 
    'case1'    'case2'    'case2'    'case2'    'case1'

MATLAB: How to write code for hankle and toeplitz matrix

My apologies! I was not thinking clearly when I wrote the nonsensical A.^(0:9). The following should produce the desired two arrays.

   M = 6;  % A is M x M, B is M x 1, C is 1 x M
   N = 10;
   F = zeros(N+1,M);
   F(1,:) = C;
   for k = 2:N+1
     F(k,:) = F(k-1,:)*A;
   end
   r = F(1:N,:)*B;
   c = [C*B;zeros(M-1,1)];
   phi = toeplitz(r,c);
   F = F(2:N+1,:);

MATLAB: How to create an array and combine and put two images into it

Maybe you need to resize or add white pixels so that the images have the same dimension.

A = imread('Yuan.jpg');
ACrop = A(300:1300, 300:1051);
imshow(ACrop)
B = imread('Jacky.jpg');
BCrop = B(1:225, 88:283);
imshow(BCrop)
[qq,ww,ee] = size(Acrop); 
matrix = 255*uint8(ones(qq,ww,ee)); %Image with pixels in 255 (White)
[rr,tt,yy] = size(Bcrop);
matrix(1:rr,1:tt,:) = Bcrop(:,:,:); %add Bcrop to the white matrix
umi = [ACrop, matrix]; %concatenate



imshow(umi)
%or

umi = [ACrop;matrix]; %concatenate
imshow(umi)

with resize:

A = imread('Yuan.jpg');
ACrop = A(300:1300, 300:1051);
imshow(ACrop)
B = imread('Jacky.jpg');
BCrop = B(1:225, 88:283);
imshow(BCrop)
[qq,ww,ee] = size(Acrop); 
Bcrop = imresize(Bcrop,[qq ww]);
umi = [ACrop, Bcrop]; %concatenate
imshow(umi)
%or
umi = [ACrop;Bcrop]; %concatenate
imshow(umi)
