Error using reshape To RESHAPE the number of elements must not change. Error in loadFileYuv (line 18) imgYuv(:, :, 1) = reshape(buf, width, height).'; % reshape

function [mov,imgRgb] = loadFileYuv(fileName, width, height, idxFrame)

fileId = fopen(fileName, 'r');

subSampleMat = [1, 1; 1, 1];
nrFrame = length(idxFrame);

for f = 1 : 1 : nrFrame
    % search fileId position
    sizeFrame = 1.5 * width * height;
    fseek(fileId, (idxFrame(f) - 1) * sizeFrame, 'bof');

      % read Y component
      buf = fread(fileId, width * height, 'uchar');
      * |imgYuv(:, :, 1) = reshape(buf, width, height).'; % reshape| *  (line 18)

      % read U component
      buf = fread(fileId, width / 2 * height / 2, 'uchar');
      imgYuv(:, :, 2) = kron(reshape(buf, width / 2, height / 2).', subSampleMat); % reshape and upsample

      % read V component
      buf = fread(fileId, width / 2 * height / 2, 'uchar');
      imgYuv(:, :, 3) = kron(reshape(buf, width / 2, height / 2).', subSampleMat); % reshape and upsample

      % normalize YUV values
      % imgYuv = imgYuv / 255;

      % convert YUV to RGB
      imgRgb = reshape(convertYuvToRgb(reshape(imgYuv, height * width, 3)), height, width, 3);

     end
  fclose(fileId);

when i was trying to run the function i was getting error in the line

imgYuv(:, :, 1) = reshape(buf, width, height).';

Kindly help me.

You are not reading what you believe you are reading from your file. I would check the size of ‘buf’ in line 17 (and probably the other such lines as well). (When I simulate Line 18 with known values, I don’t get the error.)
