blockproc换成blkproc就行,至于用blockporc怎么写,我需要点时间学学。 莫离也需要代价 亮了瞎了 9 clear;close allI=imread('cameraman.tif');imshow(I);I=im2double(I);T=dctmtx(8);fun = @(block_struct)T*block_struct.data*T';B=blockproc(I,[8 8],fun);% B=blockproc(I,[8 8], 'P1*x*...
set_param('model_name/block_name','BlockParameters',struct('Name','new_block_name')); 其中,model_name是你的Simulink模型的名字,block_name是你要修改的块的名字,new_block_name是你想要设置的新名字。 注意:这种方法可能会受到Simulink版本和具体设置的影响,建议在使用前先在简单的模型上进行测试。
