[ad_1] linspace<vec> is most likely a zero based array. With 100 elements, the last index is 99. Therefore, replace for(int i=0;i<=100;i=i+1) with for(int i=0;i<100;++i) I’ve replaced i=i+1 as I find that notation unbearable. 12 [ad_2] solved The code is for to plot naca airfoil.

[Solved] What does the following bit of code mean/do?

[ad_1] The semicolon at the end of that statement makes the if statement completely useless. After removing the semicolon, that if statement is extremely bad form, and should be either rewritten as if ( (ret_val = fgets(st, n, stdin)) != NULL ) { } or ret_val = fgets(st, n, stdin); if ( ret_val ) { … Read more

[Solved] Total Number of pixels in an image [closed]

by

[ad_1] The total number of pixels is not equal to the sum of values in your image. sumOfAllPixelValues = sum(double(rgbImage(:))); numberOfPixels = numel(rgbImage); The size on disk of an image is numberOfPixels*bytesPerPixel, where bytesPerPixel depends on the bit depth of an image (uint8 would be 8 bits=1 byte, for example. To downsample the image by … Read more
